Hi guys! Here is my issue: I bought an iPhone unlocked v1.0.2(1C28) - 04.01.13_G. Everything worked fine till now, when I was sync a video from iTunes to iPhone and when all ended the ipod app just went dead! all that appears when I tap iPod is "No Content" and when i connect it to itunes it says i have to restore it. So, my question is, may i restore it without loosing the unlock? or if i perform the unlock will it lock again to AT&T? anyone?? Thank you guys!
