Un-Jailbreaking without iTunes Restore??
Ok, so I have a situation here. My iPhone 3gs 32GB has a fried USB port. It's literally DEAD. I cannot connect to any computer no matter what. "The device has malfunctioned" message is what I get when I plug it into a computer. Although it will still charge.... Anyways I have talked to an Apple "Genius" over the phone and he is saying that it is hardware failure on their part and they will issue me a replacement. Now getting to the real question here, my phone is currently jailbroken and unlocked... which means the iPhone's warrante is VOIDED! I need to somehow remove the jailbreak so I can get a "new" phone. How can I do this?
Settings > General > Reset > Erase All Content and Settings ????
SSH into my phone and Delete jailbroken apps, exploits, and unlock?
Help!! I want to be able to use iOS4!
