Hey guys,,,hopefully u can help. I jailbroke my iPhone 4 this morning. Its untethered so obv im on 5.0.1. All my cydia apps went back in no problems. The phone restarted all day when it was needed to without any issues., Now as I sit here typing this, the phone is stuck on the boot logo and wont start. Is there anything I can do or am I screwed into restoring?
