Somewhat of a noob, be gentle (please use lube on the noob). I bought a 3GS from a friend. He did not restore the phone before he gave it to me. I used jailbreakme.com to JB/unlock, but I didn't restore before the JB/unlock. So, I can't sync to get videos/songs to my comp and now I want to. It was upgraded to 4.0.1 before the JB/unlock and still has 4.0.1. So, what is the best method to restore, then JB/unlock again? If I restore, will the os be downgraded? I don't want to brick it. thanks in advance!
