I recently received a very good offer that I need to take up on right now that involves trading my iPhone with another person. I purchased my phone off contract from Verizon directly (should I advertise as "unlocked"?) and he has a Verizon phone that he's willing to trade with me. But, where I need the help is, what do I do with the new phone once I get it? I know I'll need to clear the data, take out my SIM card and replace it on the new device, but, is that it? Do I need to fix anything or give a notice to the Verizon website, or will it automatically adjust the phone and model? And this won't mess up with my current UDP, will it? This all sounds terribly easy to answer, but I haven't traded a phone with a person before so I'm just curious about the process to make sure it works properly with my account.
