I plan on getting on the non-S cycle next year by starting a 2 year contract with the iPhone 6. The problem is that I now have a 4S which is getting slow and I desperately want LTE since I have an unlimited plan. AT&T allows an early upgrade for iPhones where the base model costs $450 instead of $200. Is it better to buy a 5 this year for $99 with 2 year contract and get an iPhone 6 next year for $450? Or is it better to buy a 5S this year for $199 and get the 6 next year? The reason I am asking is for resale purposes. Obviously I will get more for the 5S next year but keep in mind if I get the 5, it will be for $100 cheaper. So I'm wondering what the better end result will be if I am signing a 2 year contract this year, and starting a new 2 year contract next year with the early upgrade. Buy 5S for $199 and sell for a good price next year, or buy 5 for $99 and sell for a lower price next year?
