AT&T Will Give You $200 Minimum For Your Old IPhone 4

As expected, would-be iPhone 6 owners are currently wading through a torrent of trade-in and upgrade offers. It's all very, very confusing. But AT&T is being clear about one thing: If you trade in an iPhone 4, 4S, 5, or 5C, you will get at least $200 credit towards a new device.

That's pretty good, if you want a new AT&T contract! And it's especially good if you own an iPhone 4 which is about to be obsolete. If you trade in an iPhone 5S, you'll get $300 in credit. You can also get an extra $100 in bill credit "with the purchase of any iPhone when activating a new line of service with a smartphone on AT&T Next." The AT&T Next upgrade program does come with a monthly service fee, however, so you'll be giving AT&T that money back eventually.

This is a good deal, but not necessarily the best out there. T-Mobile and Sprint promise to meet or beat any other trade-in deal. T-Mobile will also give you an extra $50, if you can find someone that will offer as much as they will. In a phone call with Gizmodo last week, a T-Mobile representative said that they're offering as much as $350 for the iPhone 5S. Which is super good. So trade wisely.
