I upgraded my phone and want to sell my Droid X and all my accessories on EBay. Not sure on how to reset the phone to it's original state and swipe all my data off it? Just want to make sure all my private data is gone. Also, it is a Verizon phone, with no account/contract attached to it, so do I list it as locked or unlocked, and a Verizon phone? Thanks for your help.
