I have 16 GB FLAWLESS white 4s. Comes with a Mophie juice pack air. Im reading that the 5 will be $199 for the 16 gb. Is that $199 with a 2 yr subscription? How much would it be if I was just to go to Apple and buy the phone with no contract? If I can sell my 4s and buy the 5 and only spend $100, im way down.
