I have an iPhone 3gs i want to sell that has 3.1.3 on it with jailbreak a la Spirit and unlock a la blacksn0w. I have apps and personal data on there, and did the SHSH blob backup of 3.1.3 to Cydia right before 4.0 came out. Is there any easier way to restore it to stock than put 3.1.3 on there again (I fear it will not be accepted or some error even though I have the "blob backup" -- a noobie in that department and just followed instructions from a dev's twitter). Is there an easier way to restore the phone to clean, re-JB and re-unlock? Maybe like manually wipe all contacts, photos, and apps (that should take care of my personal data, right)? Thanks guys much appreciated. Also, only going to sell my 3GS if iPhone 4 is not unlocked before the end of the summer. I'm going to Europe in the Fall and if this isnt the case, I'll just be bringing 3GS with me .
