Sprint has an offer to pay you a certain amount if you switch to them, and you can receive up to $300 for your current phone. If I did this, I would turn in my old iPhone 4. Walmart has an offer of $.97 cents for their iPhone 5 so they can get rid of them before the iPhone 6 comes out. So if I went with Sprint now and got this $.97 cent iPhone, do you think I could I upgrade with Sprint to an iPhone 6 (5.5-inch screen!) when it comes out next month - at a subsidized rate?
