Well then maybe you should make smarter friends. Jailreaking your device opens a world of possibilites, you can finally unleash the full potential of your device and are no longer bound the the restrictions and judgement of apple. For example what gives them the right to decide if you are allowed to put adult apps on your device after all it is YOUR device not thiers. I believe we should be free to do what we wish with the devices we purchased without all apple’s bullshit

Note: I have once accidentally deleted by friend’s /etc/fstab file causing his iPod to not be able to boot. I did however fix this issue in minimal time.

Also you’ll ALWAYS be able to restore to factory settings hence revalidating the warranty as DFU mode (emergency restore mode) is built into the rom (read only) files effectively making it built into the hardware!
If you can’t restore that means it’s a hardware problem and they can’t tell what what on the device let alone if it was jailbroken.

I have on my jailbroken iPod 2G, Infiniboard (vertical scrolling), infinidock (scrolling dock), backgrounder (multitasking), sbsettings (quick toggles), winterboard (complete system wide themes), categories, stacks, overboard (expose of all your springboard pages), and the list goes on and on!! Stuff that is so advanced and system altering that apple would never allow this stuff into the appstore (they just copy it for future versions of the operation system).
Apple never planned for an appstore or apps but when the dev team jailbroke the iphone and released Winchain (developer SDK for 1.x firmware) apple patched the exploit and released the appstore to try and keep control of their device.
Jailbreakers built a copy & paste app for 2.0, 3.0 had copy & paste.
Jailbreakers made categories backgrounding and quick toggles for 3.0- and apple add these to 4.0.

On a computer you have access to your computers files jailbreaking adds that to the iPhoneOS!

Mac is finally a really good system, with the new OSX systems. The old Macs sucked period! Now…that being said…

My biggest problem is don’t try to sell me a product that I MUST buy YOUR hardware exclusively for, and pay a bloody fortune for it to begin with. Apple justifies this by saying they have exceptionally good quality hardware that is approved only for their systems. However, I can choose superb quality hardware of my own thank you, and without paying crap loads of money for it!

They make great products, decent OS, now one day when they get reasonable with prices I may even purchase a Mac…but right now I refuse to give them any of my money and they can shove their Mac Mini where the Harddrive doesn’t shine.

Objective C people, all ya need with the iPhone SDK, use a virtual install or duel boot but to NOT encourage corporations like Apple (or Microsoft) to continue to gouge people.

To None Developers: You folks want to know why you have to pay so much for software titles? Because developers have to deal with crap like this from Apple, or buy expensive IDEs from Microsoft. Not bad enough we have to keep getting re-certified and constantly learn ever changing programming languages.

They will all come back to their roots eventually, as Mac runs over BSD now so will Windows come back to their roots eventually. Don’t believe? Look at the directory structure of a LINUX/UNIX flavored machine, then look at the changes of the Windows directory structure from WinXP to Vista alone.

Anyway, keeping it simple 4u:
Jailbreaking = I can use other carrier’s Sim
