Like it says, what do I need to do to use 1.1.4 (or 1.1.3, I suppose) with a non-iPhone AT&T SIM? I see iNdependence will put 04.02.13 modem firmware on my phone, should my SIM work with that? The modem firmware is currently 04.02.13 and I can make calls, but when I upgraded to 1.1.3 before it put 04.03.XX on there and I had no carrier. I had to virginize and hassle through 1.0.2 back up to 1.1.2 to get to that again. Bootloader 3.9, 1.0.2 when I got it. Any help please? edit: I don't want to unlock, I have an AT&T SIM but not iTunes activated on an iPhone plan. Thanks.
