Apple’s mobile operating system update, iOS 4, is now available to download via iTunes.

The updated operating system, previously known as the iPhone OS, features more than 100 new features. However, in order to download the 378MB update, you will need the latest version of iTunes (version 9.2), so be sure you are all up to speed before trying to upgrade.

iOS 4 can be installed for free on the older iPhone 3G and the current iPhone 3GS, in addition to the second- and third-generation iPod touch. An iPad-friendly version of the OS is expected later in the year.

The main features that the new OS offers includes multitasking, a unified inbox, folders for better application organization, the introduction of Game Center and more. Apple’s own site has an informative run-down of what iOS 4 brings to the table.

Check out the iOS update and let us know if you have any problems.

  1. Has been available for about an hour here in the UK. Its on my 3GS now! Just got to sort out these folders… too many possible layouts!

    And i never had jailbreak or the GM version. :(

    Someone knows what to do ?

    Oh, Ibook is nowhere to be found on my 3gs to :(

    1. You need to download iBooks via the App Store.

      1. thanks, I’ve searched it

    2. GameCenter won’t be available till July 1st if I remember right… or at least “a later date”

  3. Took 1 1/2 Hours to update my Third Gen iPod and this is what I concluded. The folders work. Multitasking and home wallpaper DO NOT.

    Share
    1. That’s because you have the 3G version not the 3GS version. Time to upgrade I reckon ;-)

      1. He said he has an iPod – not an iPhone!

        Share
    2. if you have an 8 gb 3rd gen or 2nd gen multitasking will not work

      Share
  4. Why it dose’nt available in ipod touch g1 OR iphone g2?
    We need somthing new in it :'(

    Share
  5. All of the wallpaper I’ve had on my iPhone for years is now very pixelated. ???

    Share
  6. Pretty pedestrian upgrade for users of the second-gen iPod Touch. No home wallpaper, no multitasking. OS was really laggy first time I used it, but that cleared up after a reboot. It feels faster than 3.x.

    Share
  7. Bummed that it’s not available for 1st Gen. iPod Touch.

  8. Is anyone else getting stuck in the back up stage?

    Share
    1. I am getting stuck on the back up stage also. I don’t know whether to keep waiting to try cancel and restarting. Been waiting for over thirty minutes and still says backing up.

      1. Mine took a long time as well, it was about a third full, and then it just finished and moved on to the next step. Don’t trust the progress bar.

        Share
      2. me too – the progress is at what seems 0,75 % for almost half an hour and moving at 0,01 % per Minute – i hope it wont take till my iPhon 4 arrives ;-)

        Share
    2. It did take quite some time but it eventually went through. I cancelled and restarted but that didn’t make it go any faster.

      Share
      1. UpDate: It Just did not work. i let it run for more than six hours till the morning, but it was then not nearly by the 10 %, so i cancelled in the morning, And started again, but it seems, that it ist not going faster – so i think i have to cancel again, cause i need the phone

    3. You can always donwload the firware and do a “restore”….

      Share
  9. Downloading on my 3gs now, for the people with 1st generation phones and iPod touches maybe it’s time to invest in something a little bit newer since ios 4 isn’t working on your devices

    Share
  10. I cant even download it, just keeps saying my current version is the most recent

    Share
    1. …nor the iPod Touch 2nd gen it seems. When i try and run software updates it says i have the most current version … WTF

      Share
      1. My 2nd-gen updated fine. You could try downloading the firmware manually and then restoring it.

        Share
  11. I got an iBrick with this upgrade, I’m trying to recover it. :(

    Share
  12. It stupefies me that Apple cannot implement a fundamental feature such as background wallpaper on older models. As anyone whose jail-broken their iPhone or iPod Touch, and these features have been implemented on these older models. I find it humorous that the Palm Pre, HTC Hero, & many other smartphones have accomplished this feat but Apple cannot. I simply do not buy or accept Apple’s argument here. Well, looks like Apple’s given me more of a reason to enjoy my Samsung Moment & Android 2.1.

  13. Installed iOS4 onto my 3GS without too much problem, but then noticed all my photos were very pixellated and the quality had gone. Realized I had to optimize them as my photo sync settings were not set for all photos and folders, just in case anyone else found this problem. Other than that, it seems all OK, but slightly underwhelming. Folders is a nice feature but the icons on the home screen don’t look very nice.

    Share
  14. Installed the update but multitasking doesn’t seem to be working? I’m using a 3GS but when I switch apps it doesn’t remember where I left them and instead just reloads! Anyone know if apps need to be re-written or problem with update/3GS?

    Share
    1. Apps have to have state-saving built in to them. Check with the developers to see if they’re in the process of adding it.

      Share
  15. After the iOS 4 update my iPod Touch no longer works with my car dock from iCarKits.com. I can also no longer download podcast directly onto the device from the iTunes store.

  17. So I went online to update my 3GS to 4.0 and after it seemingly was going smooth, it was interrupted with error messages and left me with an iPhone with black background, and white text that looks like DOS screen. The tail end line is:
    ‘panic: We are hanging here…’

    Anyone had a similar prob? Looks like a visit to the apple store is in my future today.

    1. When I try to update my 3GS to iOS 4, I get some black/white screen (looking like DOS) full of code, with the last line saying: “Panic: We are hanging here”. By the time this happens its frozen and when i plug in again, iTunes finds a phone in restore mode. When I try to install the update again the same happens. It happens even when I try to reinstall 3.1.3.
      I tryed this on several Computers/Macs. Only thing that worked, was to restore 3.1.3 by using some old itunes version.

      Please help me

  18. I tried downloading the latest iTunes 9.2 – DONE.
    Tried updating iOS4 – It crawls slowly and then I get an error message, saying – The connection timed out.
    May be because of heavy traffic and slow internet speed here.

    Well, anyways… that’s not any issue for me.

    I made a lot of searches…
    I came to know about few websites. They are providing iOS4 file [.ipsw].
    Like — http://www.iphonexpert.com/how-to-download-ios4-iphone-ipod-touch-gm-firmware-itunes-9-2-beta/
    And, for me… the benefit is, I CAN DOWNLOAD AND RESUME THE UPDATE [via download manager] WHENEVER I WANT TO and NO ERROR MESSAGES LIKE the connection timed out.
    BUT…
    I’m very much scared about — IS THAT GENUINE APPLE iOS4?
    Please help and guide.

    I want Apple to work on their Download Manager, so that, guys like us may never need to RESTART the iOS4 download again from 0, once it fails.

    It has just been 14 days, I bought this Apple iPhone 3G S.

  19. iPod 2nd gen has been stuck in back-up for 2 hours. I’m trying to manually download the iOS4…but where???

    Share
  20. Downloaded the update. Then did the update on my 3GS. After the download, the update took 15 minutes. Nice upgrade, no issues except with apps such as MLB’s AtBat 2010 which have not been updated to run with OS4.0 yet. Battery life seems much better than before, multitasking works fine. I especially like being able to have more than one Exchange account, the unified email box makes life much simpler, like my old BB. I have reorganized my apps using folders, which I am getting used to. A good update. Seems very solid. Just works.

  21. Soo, I just downloaded the new iOS on to my iPhone 3G. I was really excited because I saw that you could have a background on your home screen, but to my displeasure I found out I could not. Although the update has many other features, I would have liked to have seen the multi-tasking as well as the fun screen background change not have excluded iPhone 3G from it.

  22. I have Itunes 10.01 is it or do I NEED 9.2?
