I have an iPhone 3GS that I'm going to sell and I'm wondering the best way to sell it jailbroken and unlocked but not have any of my data on it? Does anyone have a step by step process for that? Should I just wipe it and sell it that way? Or should I wipe it and put it on 3.1.2 or 4.01? I want do what ever will maximize it's value on ebay. For reference I have it currently running 3.1.2 on firmware 04.26.08. I have my SHSH Blobs on file from 3.1 to 4.01 with Cydia. Is it worth any more money on the old firmware now that it's unlockable on all firmwares? Also, this is a launch day 3GS with the original bootloader.
