accidentally upgraded to 3.1.3..... i was in the process of re-jail breaking, i forgot that they just released the new update and clicked restore in itunes anyway. now when i try to restore back with either 3.1.1 o 3.1.2, it gives me an error. Not compatible. i am using a 3g 8gb touch. or is it a 2g? never understood why they called it a 3rd gen 8gb. either way i tried 2g and 3g firmware and got the error both times any input is much appreciated.
