Hi there, I am planning to sell my 3gs (AT&T) that is currently jailbroken (used jailbreakme.com) and unlocked with ultrasn0w. I want to restore it to factory settings to get rid of all my private data. As far as I know, I can just restore it with the same firmware it currently has (4.0) by holding down the Shift key while clicking the restore button in iTunes. I have already downloaded the original firmware. After restoring it, I would go to jailbreakme.com to jailbreak it again. Am I on the right track, or am I missing something? How do I activate it? Does it automatically activate with the jailbreak? I have an AT&T SIM, but it's not active, can I still use it to activate? The 5th and 6th digit of the SN are 37. The Modem Firmware is 05.13.04 Thanks in advance for your help.
