I've jailbroken my iPhone before but never unlocked it. Now I'm selling my launch day iPhone and would like to know the best way to delete all of my content, then jailbreak and unlock it without having any of my personal info. on it. I will be shipping it without my sim card obviously. So far the steps I'm thinking are: 1) Erase All Content and Settings (Settings > General > Reset ) - I assume this step will get rid of all of my personal information I'm not sure what steps to take next are. I obviously do not want to sync with iTunes.
