So I downloaded something from cydia from the source sinful iphone source. After I downloaded it, while it was installing, my iphone stopped responding. I had to let the battery die, then when I recharged it, while it was turning on it froze at the apple logo. So I put it in DFU mode and restored it and now my iphone is all messed up. After I restored it, it shows the recovery sign and the slider now. But when I slide it, it only shows me the emergency call. I have my sim card inside and itunes can't read it. My Iphone doesn't read it either. I'm with Fido. I think my think iphone is a 3g with the firmware of 3.1.1. Of course my iphone was previously jailbroken. Can anyone help me fix my iphone back to normal? I'm dying here.
