I've done a bit of searching and keep seem to find a definitive guide on how to prepare my iPhone 3GS for resale on eBay or Craigslist. I'm afraid to do something wrong as it might cause my iPhone to become stock and to lose the unlock. Some information about my iPhone: Jailbroken using PwnageTool Unlocked using Ultrasn0w Version = 3.1.3 (7E18) Modem Firmware = 04.26.08 I want to sell it as Jailbroken/Unlocked so keeping both of those states is a must. Thanks in advance for any help. Also wanted to add that I have my 3.0, 3.1, 3.1.2, 3.1.3 SHSH's on file.
