How to Restore Unlocked and Jailbroken 3G
I just got a new 3Gs and would like to get rid of my 3G.
My 3G is unlocked (UltraSnow) and jail broken (RedSnow), however, I would like to sell it and have it reset back to the original settings while maintaining the unlock. I have been reading that if I do a factory restore through iTunes it will get rid of my jailbreak and will permanently lock the phone.
How do I restore the phone (get rid of all my private data) and still have it unlocked?
