So here's the story. A friend of mine has a jailbroken 3G. One day, the screen refused to turn on but he could still hear calls and text messages coming in. Rather than hard-rebooting or restoring the phone, he took it to the Apple store and the "Genius" noticed the Pwnapple logo when he tried rebooting the device. He said the Genius became very rude and accusational, then proceeded to enter his IMEI into the computer at the store. The Genius tried to say that Cydia had "burned the IMEI number" in the phone, which is absolutely ridiculous. He then mentioned something about the phone now being flagged, saying that my friend would have to pay $200 for a replacement phone. At this point the phone was on the Activation screen requesting that it be connected to iTunes. Back at home, iTunes refused to reactivate the phone. He gave me a call and I came over to repwn it, so that he could at least get to the home screen. It worked, but he is unable to get any signal WHATSOEVER. We've tried a different AT&T sim, no difference. It's as if the phone was reported stolen. We're trying to figure out how we can get the phone active again, I was thinking maybe a proxy SIM would work because it may fake the IMSI or IMEI, but that's the only idea I could come up with. Has anyone else had this experience or have an idea how we can get his phone working again? Please share your experiences, it's unbelievable that they legally have the ability to do this.
