The phone with its own Facebook button, the HTC Status, is set to hit stores July 17 and available for pre-order now.
The phone will be $49.99 with a two-year contract on AT&T and requires a minimum $15 per month data plan.
HTC is touting the phone as being context-aware, meaning that the Facebook button lights up when it senses a user is doing something he or she may want to share, such as listening to a song or viewing a photo on their phone.
The phone itself is an Android-based handset running Gingerbread 2.3, with an HTC Sense overlay. It has a 2.6-inch touchscreen, up to 512 MB of internal memory, and comes with a 2GB microSD card.
