I'm in the process of selling my 8gb iPhone 3G, and I'm wondering what steps I should take before hand. Some specifics - the person buying my phone is sending it overseas (for what, I do not know). He's picking it up on Monday, so I'll be without a phone until that Friday. - Do I remove my SIM card? - Should I cancel my AT&T service for the next 5 days so charges don't get applied to my account, or does removing the SIM card prevent that from happening automatically? - I'm going to wipe all the apps off of this current phone so it's as close to factory as possible, but are there extra steps I should take? Any help would be awesome, thanks guys.
