Amazon Wireless is selling the HTC One X for $129.99, a $70 discount on the usual price, and the offer is open to both new and existing customers of AT&T. This would be a great time to upgrade to our best-reviewed phone of 2012 so far, assuming you don't mind extending your AT&T contract by a couple of years. One small catch is that the offer only applies to the dark gray version of the phone right now, with the white model backordered for the next few weeks. We're rather partial to the white One X ourselves, but perhaps you'll find the gray model more to your liking. If so, hit up Amazon to find out more about the particulars of the deal.
