Photos from Chinese microblogging site Sina Weibo clearly show huge crowds at the two Beijing and three Shanghai locations, despite temperatures between 32 and 40 degrees Fahrenheit. The lineups are likely for people who want to try to get an iPhone off-contract and unlocked, starting at 4,988 yuan, or around $790. Shoppers can also buy directly from China Unicom, which even has some pricing plans that allow users to pick up the hardware free, but monthly contract requirements for those subsidies are quite steep. Plus, buying unlocked makes it easier for scalpers to resell devices through unofficial channels.

When it launched in the U.S., the iPhone 4S was also greeted with long lines, and in Hong Kong, attendance at Apple’s retail flagship store numbered in the thousands. The Chinese launch of the 4S should be the biggest since it debuted in October, since China is now Apple’s second-most-important market, and according to at least one estimate, it’s conceivable that Apple sold more iPhones in China during its fiscal fourth quarter of 2011 than it did in the U.S.

The staggered launch means that sales resulting from the Chinese launch of the iPhone 4S will appear as part of Apple’s second fiscal quarter results and not those that will be reported on Jan. 24. That could help Apple post higher iPhone shipments next quarter even without the holiday bump, especially if its regulatory progress with getting a China Telecom-compatible version of the 4S to market bears fruit within the next couple of months.

Mophie’s Juice Pack Air for the 4th generation iPod touch is one of two battery cases being recalled. It can, in very rare instances, become so hot it can potentially cause burns to a user. Mophie says it only happens in very rare cases, but the heat is enough to deform the case in many more instances. If your product has a serial number starting with TR113 through TR120, you’re eligible to receive a replacement product, which you can get following the instructions found at Mophie’s replacement website.

Best Buy’s in-house brand Rocketfish is also having heating problems with its battery case for the iPhone 3G and 3GS. The situation is a little more extreme for those accessories, however, as Rocketfish is saying those overheating issues could in some cases lead to a fire during the charging process. There are 14 reported incidents on record, some of which include minor property damage. Affected owners will be reimbursed with a gift card for $70 or $105 depending on whether they’re located in the U.S. or Canada, respectively. Check your eligibility and find directions for getting your gift card at Best Buy’s recall site.

If you’re a battery case user, you already know they tend to get hot, but in both these cases the situation is going beyond the average levels of heat and into dangerous territory. Had any incidents with the products described above? Let us know in the comments.

• Why iPad 2 Will Lead Consumers Into the Post-PC Era

A lot of factors are involved in choosing a new device, and people might be understandably reluctant to drop a lot of money on new hardware now, given the current global economic climate. How you use your device will also ultimately determine whether new features are worth the investment. So consider the following before making up your mind.

Is your contract up?

Carrier subsidies are a huge boon to cell phone buyers. With subsidy, the new iPhone 4S costs between $199 and $399, depending on how much storage you want on your device. Off-contract pricing in the U.S. hasn’t yet been announced, but in the Canadian store, it’s listed as starting at $649 and going up $100 for each additional level of onboard flash storage, topping out at $849 for the new 64 GB tier. U.S. prices should be in the same ballpark, if they don’t match those exactly.

A difference of $450 is going to be a difficult pill to swallow for most. Unless a brand new iPhone is a valid business expense for you, or necessary because your existing phone is actually broken or failing, you probably shouldn’t upgrade if you can’t get the subsidized pricing unless you’re really interested in Siri, but let’s take a look at that particular buying incentive.

Siri looks good, but so did FaceTime

Siri plays well in Apple’s promo videos, and it was impressive during the Apple presentation Tuesday, but those things don’t necessarily make it a must-have. Many are pointing out that using Siri in public will be downright awkward, and there’s also the comparison Stacey drew to FaceTime: How many will actually use Siri with any kind of frequency or consistency?

If Siri is the only reason you’re thinking about upgrading, then taking a step back and waiting might be your best course of action. Siri isn’t going anywhere, after all, and a couple of months of it being on the market might give us a better idea of its usefulness in everyday situations.

Will you be upgrading anyway?

Some might be tempted to consider upgrading an older iPhone (a 3G or 3GS, for example) to an iPhone 4, given that device’s lower starting price point. But if you’re already going to be upgrading, and likely locking in to a new contract anyway, consider that by the next time you become eligible for a phone you’ll be two devices behind instead of just one. That isn’t working out so well for 3G owners right now, since software support ended with iOS 4.3.

A faster processor and dual-core graphics might not seem like big advantages today, but the gap will widen; the iPhone 4 will become slower and less reliable with each subsequent software update, while the iPhone 4S is better able to take advantage of its increased power. Even if you think you can live without Siri, a better camera and faster networking (which will also only get better and make older devices look worse as time passes), you should seriously think about paying up for the iPhone 4S.

How important is your carrier?

If your choice of carrier is a key factor in prompting an upgrade, then now’s a good time to move to the 4S. Sprint availability is going to be great for some, especially considering the availability of unlimited data plans on that network. If you want a new iPhone because you’re looking to improve your network reliability, then the 4S is an especially good choice because of the new, speed-boosting dual-antenna design.

In summary: The iPhone 4S isn’t a disappointing upgrade, no matter what tech pundits and analysts may say. But just because it isn’t disappointing doesn’t mean it’s right for you. Before you decide to stay up late and hit the iPhone pre-order page, consider the above, and should you think of anything else that’s worth considering, share it with us in the comments.

iOS 4.2.1 Update Tested

To test how iOS 4.2 affected performance, I took an iPhone 3G and ran it through the same series of performance tests I did when iOS 4.1 was released. Just like last time, I used GeekBench 2 ($1.99), Gauge Mathematical Tool ($1.99), BenchTest (99 cents), SunSpider (free) and V8 (free) to test the performance of each OS version on the 3G.

Also like last time, the 3G I was testing was still running with a lot of features disabled, and was being used more as an iPod touch than as an iPhone. I am reusing the same data collected last time for comparison. The following results are only a subset of the data collected, and focus on the data points that changed the most from version to version:

Results for iPhone 3G: The 4.2.1 Update

While some things seem to have improved slightly, like JavaScript and drawing new content when you switch views in an app, other tests have dropped off considerably. Memory performance as measured by GeekBench, as well as the executions of Gague’s Prime Number test are especially bad. These would affect apps that are doing much more than just displaying or editing a simple screen, like an RSS reader, for instance.  It would have a greater impact on apps performing more advanced computational functions, such as Documents to Go.

Just informally trying out several core apps like Apple’s Notes, Safari, Calendar and Contacts revealed more than the benchmarking tests indicate, however. Scrolling speed and data entry appear to be much improved. It seemed as though my performance tests were contradicting my real world experience.

One More iPhone 4 Test: The 4.2.1 Update

Testing on the iPhone 4 was the best way to find out if the performance degradation I was seeing on the iPhone 3G in the tests was really something to worry about. I reused the same benchmarking data collected in earlier tests for comparison. I was looking for the same degradation in performance in the same areas.

Since both the GeekBench Stdlib Allocate test as well as the Gague Prime Number test degrade on the iPhone 4 as they did on the iPhone 3G, I had to conclude that it was an issue with how the test was seeing changes made to the iOS firmware in version 4.2.1, and not necessarily a reflection of actual device performance.

Conclusions

While data entry, scrolling, pinching and zooming have improved slightly, the 3G is still not up to par with its newer siblings. Where we see the most gains on both the iPhone 3G and the iPhone 4 is in the JavaScript results.  Whatever the Webkit/Safari team is doing, it is having a positive effect with each release.

Bottom line: If you’re still using iOS 3.1.3 and use sophisticated apps that are heavily computational, then it’s probably best to avoid 4.2 (that’s easier if the apps you’re using don’t require 4.0 or higher). If you’re content with the apps Apple provides and mobile Safari, you should be fine. If you need the more demanding apps, and those apps need iOS 4.0 or higher, it might be time to consider that hardware upgrade.

The lead plaintiff in the case, Bianca Wofford, claims the update effectively turned her iPhone into an “iBrick,” rendering it pretty much unusable. She says Apple informed customers that iOS 4 would be an upgrade for their 3G phones, even though it wouldn’t bring all of the features that later devices would get. Instead, she got a device that’s not only much, much slower, but also prone to crashing.

The complaint, filed with the Superior Court of California, asserts that Apple did this knowingly:

Since the release of iOS4 in conjunction with the sale and release of the fourth generation iPhone, or the iPhone 4 in June 2010, Apple has falsely, intentionally and repeatedly represented to owners and consumers of the iPhone 3G that its new operating system for the device, iOS4, was of a nature, quality, and a significant upgrade for the functionality of all iPhone devices, when in fact, the installation and use of iOS4 on the iPhone 3G resulted in the opposite – a device with little more use than that of a paper weight.

Wofford and her attorneys further justify this claim by pointing out the Apple practice of not allowing customers to downgrade their iPhone’s operating system. She says there isn’t a way to get back to iOS 3.x without resorting to “hacker tactics” that void warranties and iPhone user agreements.

All of these, taken together, amount to an intentional move by Apple to force customers into a situation where they’d have to purchase new hardware in the form of the iPhone 4. According to Wofford, Apple knew full well that iOS 4 was actually a downgrade for older devices, and used its release as an artificial upgrade incentive.

Wofford is seeking restitution, the return of Apple’s “ill-gotten” gains and damages resulting from false advertising, unfair competition and the violation of state consumer protection laws for herself and each member of the plaintiff group associated with the class action suit.

Is Wofford right? Apple has held back updates in the past from legacy hardware, presumably because it knew those devices weren’t up to the task of running them. It must have conducted tests in-house to determine how well iOS 4 worked on older iPhones before releasing the software. But then why release a limited version of iOS 4 for the 3G and 3GS, instead of the full one if its intention was to slow performance? Maybe the full update rendered it actually unusable instead of just badly hobbled?

Regardless of the accuracy of the claims, Apple will probably move quickly to either quash this or settle out of court, since it could be potentially damaging to its reputation among consumers. If the upcoming iOS 4.2 brings any relief to iPhone 3G owners, that could go a long way toward preserving that reputation.

What do you think? Did Apple intentionally encourage iPhone owners to do harm to their own devices? And even if not, shouldn’t they provide a legitimate downgrade process in instances where performance, stability and usability are affected?

Next Gen Customers on Previous Gen Devices

The most likely recipients of older iPhone 3G devices will be the siblings of the owners of the devices which have replaced them with the new iPhone 4. This is a very important class of user that Apple cares a lot about. The new owners of these older iPhone 3G devices will be potential Apple customers throughout their academic life. And it appears that students are serious about Apple. Providing a less than awesome experience now could jeopardize their loyalties later.

One iOS to Rule Them All

The current burden on developers targeting Apple’s mobile devices is that there are too many software versions to manage; 3.1, 3.2, and 4.0, to name a few. The number of devices on each of these three major platforms is still significant. With the upcoming iOS 4.1 update, Apple has the opportunity to converge more of these devices to just one OS platform. That is, if they can convince iPhone 3G owners that performance is no longer an issue.

Focusing on multiple platforms does take time away from adding features and releasing new titles. Giving developers the tools they need is only part of the equation. Switching between simulators and managing several different devices takes time. Cutting down on the number of device and OS combinations that developers need to support will only strengthen the quality of the apps for devs that don’t test across the matrix of combinations, and give back some development time to those that do.

Engineering Pride

Apple has been quite public about the engineering capabilities of other software development shops. Apple was also adamant all along that iPhone 3G devices would be supported on iOS 4, minus some features. Nonetheless, Apple proclaimed support for these devices. Taking on its own challenge, stepping up to the plate and delivering an awesome experience to its next generation of customers is what Apple’s core values are all about.

You’ll need an iPhone 3G or iPod touch 2nd-gen, as well as the redsn0w jailbreak, which you can download from here. Now you’re set to do the real work, but first a disclaimer: the procedure is rather simple, but be warned that you could easily brick your device if you’re not careful. Also, jailbreaking will void your warranty, so be smart and restore your device with iTunes before you take it down to the Genius Bar.

Got it? Great.

If your device is still running on iOS 3.x, you’ll need to upgrade to 4.0 before you proceed. Just go into iTunes, click on your device in the sidebar, and check for updates.

The Nitty Gritty

1. When you start-up redsn0w, you’ll need to point it to the iOS 4 IPSW, which, if you’ve already installed iOS 4 on your device, should be at ~/Library/iTunes/iPhone Software Updates/ and will be named something like iPhone1,2_4.0 for the iPhone and iPod2,1_4.0 for the iPod.

2. If you’re using an iPod, redsn0w will ask you to clarify whether it’s one of the newer models that start with “MC.” You can check this by going to General -> About on your iPod and scrolling down to “Model.”

3. Now you can decide what features you want redsn0w to enable. You can choose to install Cydia (which is like an unwalled version of the App Store), Verbose boot (which gives you every detail of what’s going on while your device boots), Custom boot logo, and Custom recovery logo. That’s nice, but you can also enable multitasking, home screen wallpapers, and the battery percentage indicator, which are the really great benefits from doing this.

4. Connect your device to your Mac and turn it off by holding down the lock button until a red slider appears, which you should then slide. Make sure your device is completely off before you continue, meaning there should be no spinning progress indicator, or anything, on the screen.

5. Be prepared for this part, because redsn0w will start on this step immediately once you click “Next.” You’ll need to put your device into Device Firmware Update (DFU) mode. redsn0w will walk you through it, but you’ll need to be quick. The process basically goes like this:

• Hold down the lock button for 3 seconds
• Without releasing the lock button, hold down the home button for 10 seconds
• Without releasing the home button, let go of the lock button and continue holding the home button for 30 seconds, though redsn0w should start doing its thing before the 30 seconds are up. Once you see a grey background on your screen, you can let go of the home button.

6. Watch while redsn0w jailbreaks your device and enables all the features that Apple left out. Do not yank the device of the cord, no matter what happens. That’s a recipe for bricking your device. Just relax and go get some coffee, or drool over the new Mac mini. When you come back, your device will be running with all the features you envied the 3GS for. Tip: You can enable the battery percentage indicator by going into Settings -> General -> Usage and turning it on.

How does the old hardware handle multitasking?

4.0 was already sluggish for me without multitasking. Rest assured, your performance won’t improve if it was already sluggish. But it hasn’t gotten worse, at least on my device, and if you’re going to use a sluggish OS, you may as well have all the features enabled, right?

Is your device running faster after the 4.0 update? Slower? Tell us about your experience in the comments.

Battery Percentage

Many users were disappointed to learn that Battery Percentage is exclusive to the iPhone 3GS, and not a general feature in iPhone OS 3.0.

There are two ways to turn on the battery percentage in the jailbroken iPhone OS 3.0.
1. Through SBSettings
If you have SBSettings installed, simply tap on “More,” then “Extras.” There you will find Enable/Disable Numeric Battery.

2. Through AsBattery
If you prefer to have the stock Battery Percentage toggle found only in the iPhone 3GS, you’ll need AsBattery. To install AsBattery:

1. Fire up Cydia.
2. In its “Search” section, type in iPhone-notes. What you are doing is looking for the repository that AsBattery is hosted in. Install this repository.
3. In Cydia’s “Changes” section, look for “AsBattery” and install that.
4. Reboot your iPhone.

Once you’re back in, the battery percentage toggle will be present in Settings → General → Usage.

The magic that AsBattery does is it adds the string gas-gauge-battery to a file called M68AP.plist (if you have an iPhone), N82AP.plist (if you have an iPhone 3G), N45AP.plist (if you have an iPod touch 1st-generation), or N72AP.plist (if you have an iPod touch 2nd-generation).

Video Recording

Jailbreakers have long enjoyed Cycorder, a free app that records video in MPEG 384 x 288 at 6—15 fps, depending on lighting conditions. Sure, it’s far from the 640-by-480-pixel at 30 fps capability of the iPhone 3GS, but, hey, I’ll take some video over no video any day. It’s better than nothing.

Voice Control… somewhat

If you’re so inclined towards voice dialing, there’s always Vlingo and Melodis Voice Dialer. Both apps work pretty well, though you can’t do neat stuff like ask your iPhone what song it’s currently playing (and have it reply!). One other notable voice-related app is, of course, the Google Mobile App, though it should be noted that this app does not do voice dialing.

Vlingo has one neat feature. You can dictate a status update for your Twitter or Facebook account.

Isn’t North Always Up?

Sorry, it’s a hardware limitation. But it’s not that bad. Do a search for “compass” in the iTunes App Store and you’ll find a plethora of apps purporting to show you the way to The Great North. Most, if not all, of these apps require you to be outdoors and to be actually moving, since they employ GPS to find out your bearing.

If you are in a built-up area, there is an easy way to find our which way north is. Fire up Maps and let it find your current location. Since all maps are drawn with north pointing up, all you have to do is do a visual survey and orientate your iPhone so that any roads around you line up with their counterpart on the map.

But if you’re out in the middle of nowhere with no distinguishable landmarks, you’ll have to settle for sticking a compass on the back of your iPhone.

All the goodness of iPhone OS 3.0 aside, the one thing you’ve probably noticed after updating your iPhone or iPod touch is how quickly its battery is draining.

I certainly did, along with many other users. The battery life of my iPhone 3G is now barely six hours, a huge departure from the 12+ hours or so I would get with 2.2.1. And even though I’d experienced a decrease in battery life with the beta builds of 3.0 back in May, the battery never drained at a rate as alarming as this. Now, it depletes 10 percent every hour even while the phone is left doing absolutely nothing.

My first thought was that push notification must be the cause of this. But even after turning off push notification, the battery continued to drain at an alarming rate. After some investigation, it would seem that the culprit is, instead, iPhone’s push mail setting.

To turn off push for all mail accounts, follow these steps:

1. On the Home screen, tap the “Settings” icon.
   
2. Tap “Mail, Contacts, Calendars.”
   
3. Tap “Fetch New Data.”
   
4. Turn off “Push.” This turns off push, in one step, for all email accounts that are enabled for it, while preserving the “Fetch” settings you may have already set for every account.
   
5. Reboot your iPhone. To do that, hold down the Sleep/Wake button (the one at the top) until you see the red slider appear, then drag the slider.
   

After your iPhone has restarted, you should see an improvement in its battery life. Leave a comment, and tell us if this works for you!

I’m already on record saying that I think AT&T’s upgrade pricing for iPhone 3G owners is not only comparable to the industry, but maybe even a little better.

Despite what could already be considered reasonable terms, AT&T has responded to the complaints by shortening the contract duration for 3G owners to be eligible for the full subsidy:

We’re now pleased to offer our iPhone 3G customers who are upgrade eligible in July, August or September 2009 our best upgrade pricing, beginning Thursday, June 18.

This means you can get a full subsidy having used the iPhone 3G for as little as nine months out of a 24-month contract. There’s a FAQ about the changes, and also a video. Nicely done, AT&T.
