So I’m one of the lucky 600,000 that reserved an iPhone 4 for launch day. Once I get the new phone I want to sell my iPhone 3G on eBay. I know I will need to do a full Restore through iTunes to wipe all my data from the phone and revert it to it’s original state (is that all I need to do to ensure any and all of my data is wiped) but anything else I need to do? Do I yank the SIM card as well and have the buyer insert their own?

Any tips on this would be appreciated. 6 More Days!!
