Cannot unlock after upgrade to 3.1.3
I have accidentally upgraded to 3.1.3 and since then I am no longer able to unlock my iPhone. I was in a unlocked version (via Pwnage) of 3.1 before.
Unfortunately I have not found a way to restore to this unlocked version as I do not have an AT&T SIM card (the phone was bougth second hand) and of course iTunes wants me to unlock the SIM 1st, which I cannot do.
I have followed the procedure from the site iClarified but the process fails for me at the Step eleven as my Iphone does not reboot at all after entering the DFU mode.
Any chance to obtain the help of someone ? Or a way to restore without iTunes ?
Thks in advance.
How to restore the Firmware without iTunes ?
Would someone know how to restore the firmware (.ipsw file) from 3.1.3 to 3.1 without going through iTunes ? I need this as iTunes does not regonised my iPhone probably because it is not activated (I need to unlock it).
THks for your help.
