Hey everyone, I just had a couple quick questions. I am planning on trading my black iPhone 5S for a gold one. The person contacted me through Craigslist, so we are going to meet tomorrow. Besides the basics like checking for scratches and stuff, is there anything else that I need to check for? The service is through Verizon, so I'm basically wondering if after we traded he could like blacklist the IMEI and I couldn't use the phone? I think we are going to meet at the Verizon store, if that makes any difference.
