Yep, yep, nope.

Allow me to explain... When you restore your baseband and then restore the phone's OS, you go back to the original, unpatched, unhacked, unjailbroken state. It is as though you have never turned on your phone before.

Projectle,

I wanted to know if you can switch back to AT&T. I have the iPhone 3G. I bought it jailbroken and unlocked. Can i restore it and still use it with my SIM? Do i have to bring it to the apple store?
