I've pwned and loaded the custom unlocked and jailbroken 1.1.4 firmware on my 16GB iPhone using PwnageTool 1.1.
One of the speakers of my phone is not working now and I have to send it in for repair. How do I completely unvirginise it so that Apple cannot detect any trace of my activities? Will just restoring the original firmware from within iTunes do the job?
Also, if I insert an already activated AT&T SIM card from another iPhone into mine, will I have to reactivate it or something? I was thinking that I would just restore using iTunes, put in a genuine, activated AT&T SIM card from another iPhone and send it in to Apple. Would I be doing something wrong?
It's kinda urgent so a quick reply would be very appreciated.
