I upgraded from the iPhone 4 (which I got for free thanks to my company). AT&T says I'm eligible in 18 months for the new iPhone which I have no desire to get if it's a 5S (can't believe people fell for that upgrade with the 4S..complete morons). It's the perfect loop of phone upgrades because I sold my iPhone 4 for exactly what I paid for the 5. Sure my carrier rapes me on the subsidizing I guess over two years but I never have to pay for a new phone. That's one of the great things about iPhones. They hold their value even after two years. Does anyone want to guess what the Samsung S3 will be worth in two years?
