Well I'm on the share everything plan and I don't know how to get just a sim card from verizon to put into an unlocked phone (assuming I buy an unlocked phone from craigslist) The reason for switching is that we have absolutely no reliable service at our house anymore for the past few weeks and at&t isn't doing anything about it. Also, the rest of my family could care less about getting an iPhone, they're content with low end android phones. Right now, my only option seems to be trading the iPhone 4S in for maybe $200 when the iPhone 5 comes out, still gonna cost me around $450 but I guess that's a little bit more manageable...
