Is there anyone who upgraded to an iPhone 5 with a new 2-year contract when it was released (Sept 2012), and planning on getting the new 5s? If so, what is your strategy for spending the least amount of money possible? I suppose I'll go first. I have AT&T, and they offer an early "partial discount" upgrade after just 1 year. With this, (I believe) the 5s 16GB is $450 and the 32Gb $550. I can try to sell my current iPhone 5 on eBay for as much as possible, then use this towards the 5s purchase. If I do manage to get $450 for it on eBay (since its still pretty good condition), that will be enough to cover the cost. Only downside is, my contract would be renewed to a new 2-year only after 1 year. Any other plans or strategies?
