I am trying to jailbreak a friend's iphone but she doesnt knows what iphone she has. is it 3gs or 3g ??? How can i find out?
Is there any program or ..???
The way I've always did it was I use Spirit, and whenever you plug a device into the computer Spirit tells you what device it is and what firmware it's on.
An easier way is you can download TinyUmbrella or if0rcast.
