ok, took the plunge and bought IPSF, followed the instructions, upgraded to 1.1.1, prepared to downgrade to 1.0.2 again, entered DFU mode, iphone screen displays cable and itunes icon, but when i try to restore to 1.0.2 i get the error "iphone can not be restored, (error 1,5,6)"

and it is driving me MENTAL!!!

no phone is worth this. i'm honestly questioning my apple fanboy status.
