Hey there, I have a very troubled iphone. It is second hand and was jailbroken and unlocked when I got it. It originally failed when I accidentally clicked update, got the whole emergency screen/sim card not supported. I took it to a guy I know, and he got it working like a phone (re-jailbroke it I believe) but it still wouldn't sync with itunes (SIM card unsupported error) On the advice of many forums, I bought an AT&T SIM card and reset the whole thing (I know, dumb). Now it is a brick again! The screen is the itunes icon and USB cable image, when I plug it in itunes says its in recovery mode, so I click restore, and then I get an error that it can't restore (1015) I've tried most of the fixes I've found online, like RecBoot, or endless restarts and DFU cycles. I've tried restoring it with 3.1.2 and 3.1.3, SIM card in, SIM card out, Vrigin SIM card, AT&T SIM card. Help!
