Wal-Mart 16 gig iPhone 5 is $98 with 2 year contract. I'm thinking about upgrading from a iPhone 4 to 5 at that price. I have to make up my mind fast. I want a phone that will still be fast for at least two years. I seen some people say iOS 7 is slow on 5? Is that because its beta or because the processer is a little on the slow side. The iPhone 5S is maybe going to have a 30% faster processor will that make a big difference then the 5's? I don't really care about the touch sensor (unless its amazing) or duel LED and different colors.
