For those that are already on contract and looking to upgrade with a contract extension, or add a new line to their account, the price is $99 which is the same price as getting the One X direct from AT&T. The timing is perfect since it looks like the One X will be getting an OS upgrade to Android 4.1 Jelly Bean in the very near future.
Both the grey and white models are available. If you have been on the fence and want to know more about the phone, check out our in-depth review of this very capable Android device.
