I ordered a 5S last Friday and I'll have it by Wednesday. I'm already on Verizon and was not eligible for an upgrade, so I paid full price. My question is, do I need to do anything to the phone when it arrives to use it, or has Apple already configured it to work on my plan? The reason I ask (and I know I'm going to get yelled at for this) is that I can easily wait the month for them to be available in stores, and I see people selling on craigslist/ebay for twice what I paid. I didn't order it to sell, but if someone's willing to pay that much, and I don't mind waiting, why not? Thanks very much in advance!
