I have an IP4 and I recently download an app from cydia like any other day but this time it bricked my phone while it was rebooting. It was stuck on the skull mode. Im panicking dont know what to do. It seems i may have to restore through itunes but im using Gevey on 4.2.1 and i want to preserve my baseband while i restore so i can keep my unlock. What can i do. I really need some help!
