My iPhone 3G is getting "No Service" from AT&T after I attempted to quick-pwn my phone. I downloaded a clean 2.1 .ipsw update, and restored my phone, but still no luck. I also tried "reset network settings" in the settings menu.
Does anyone have any other suggestions? And additionally, if I take the phone to AT&T or Apple, will they somehow know this problem occurred through quick-pwn, even though the phone now appears to be completely at Apple's default settings?
