I currently have a jailbroken AT&T iPhone 4 on 4.3.1 that I want to sell on eBay. Before I do that I want to remove all my information, but I would prefer to sell it unlocked to get more for it. Restoring or "Erasing All Content" would remove my jailbreak - can I jailbreak it again after restore without activating it? Can someone help walk me through the steps it takes to remove all my content but then jailbreak/unlock the phone prior to sale? I've jailbroken and unlocked phones before, but always while the phone is activated and with my SIM in it.
