I need to restore my unlocked iPhone. I have made a backup through iTunes and after that iTunes did not recognize my SIM anymore.
I am using Version 2.2 (5G77, Modem Firmware 02.28.00).
On other topic I read that using quickpawn should resolve the iTunes issue. Is it possible to use Quickpawn 2.2.5 tool to activate the phone in the 2.2 version so I can use iTunes again? I am unable to upgrade to 2.2.1.
Help is much appreciated!
