Hi, everyone. i bought an iPhone 3G from a friend and it shows a blank screen. but when i slide to unlock i can here the click sound and when i connect it to iTunes it detects and work fine. can sync and back up. iTunes shows its firmware as 4.1 so it seems like the base band would be changed to iPad base band (but not sure). I am not using an official carrier and it needs to be unlocked. now it is unlocked using ultrasn0w (my friend told me). Actually what I wanted is to recover the iPhone without losing any data. My friend request me that he needs the contacts in it. Is it possible to recover or make it workable without installing iOS or if i have to, do i have to downgrade it to 3.1.3 or any other solutions. I know its simple for the devs out there. So pls help me on this. thanks in advance.
