hey i need some help please
i've got a second hand Iphone 2g wich is on 1.1.1 unlocked and jailbroken.
i don't know its history, if it was out of the box on 1.1.1 or upgraded from older versions.
i need to upgrade it to 2.1 using pwnage tool.
My question is whether do i need to virginize it first? or i can direcly use the 2.1 firmware file?
10x for help
