How to restore jailbroken iPhone 3G?
What happens when you jailbreak your iPhone 3G?
- The warranty for the iPhone is scrubbed the moment you jailbreak your iPhone. Apple is no longer responsible for replacing or repairing your device after pwning.
- You will not be able to launch any applications downloaded from the App Store. Even those applications that you installed before the jailbreak will freeze.
- Many problems will surface if you restore the backup you took before the jailbreak.
- You have no more relation with the App Store.
Now you regret that you made your phone somewhat useless and want to de-pwn? How to do that?

Open iTunes, click on Store and Deauthorize your computer from iTunes and Sync your iPhone. When the syncing is done, reauthorize your iTunes and sync your iPhone again. That’s it, never jailbreak your iPhone 3G again.

Is this a joke? All apps downloaded from the App store work perfectly fine on a jailbroken 3G iPhone. The app store is accessible and you can purchase or download free applications from the apps store.
If you decide to revert back just do a full restore from iTunes.
If you’re iPhone needs to go in for warranty just backup, restore and turn in for warranty repair. When you get it back, jailbreak and restore from backup.
Hi John,
Your experience, applications working on a jailbroken iPhone 3G sounds strange. For some reasons, it doesn’t work for me, may be something is wrong :-). Thanks for the comment
I just jailbroke my 3G in 2.1 and my old apps work perfectly fine. Cydia, Installer, and the App Store are all on my home screen and all fully functional. I haven’t needed to restore from a backup of my jailbroken iPhone so I can’t speak to that issue.
I think this article is Apple propaganda to the extreme cause non of the original post is true at all.
I jailbroke my Iphone 3g 16g about 2 months ago it’s been great I have tons of new apps, till recently my phone cant make no calls check my voicemail or look at my contacts, everything else works, fine I can recive calls only, can any one tell me what’s wrong with it how can I fix this pls asap….
Restore back to original OS using iTunes. Then jailbreak again and restore from backup. Although I would look at any apps you have installed recently that may of caused your phone to stop functioning.
hey chris i know what your going through a word of advice… STOP JAILBREAKING YOUR IPHONE!!! i did that i restored and restored and restored and guess what my phone does not work…and iTunes8 blocks the restoring of a jailbroken iphone/ipod touch! i need to get it fixed but dont know how
chris a i think i experienced the same problem. what i did was i uninstalled all the apps i had installed before the problem surfaced. and i discovered that it was the program kate. uninstall kate and youll be fine.
kate caused my iphone 3g to have problems with the contacts as well. deleted it and now everything is fine.
The same thing happened with my iPhone 3g after I installed Kate but I restored it and works again and you can restore a jailbroken iPhone 3g using iTunes 8
My apps did stop working once I jailbroken my phone, but once a downloaded a new apps from the apples store they all worked again and I have and iPhone 3G.
This HAS to be a Joke…The Pwnage Tool Was released by the iphonedevteam and works perfectly with ALL apps from app store and cydia sources. This is Apple propaganda if you ask me
pretty sure this was tongue in cheek, guess it worked
