(Pocket-lint) - Facebook has officially announced the HTC First "Facebook Phone" at a media event at its headquarters in San Francisco.

Peter Chou, HTC's chief executive officer, revealed the handset based on Android with Facebook's own Facebook Home launched on top. It's the only handset right now to have Facebook Home pre-loaded. 

The HTC First will be available in four colours: red, baby blue, white and black. It will be available on AT&T on 12 April for $99 (£65) with LTE on-board. In the UK, EE has announced it will be carrying the HTC First in the summer as an EE exclusive.

The HTC First features a 4.3-inch 720p display, 5-megapixel rear camera, 1.6-megapixel front camera, 1GHz dual-core processor, LTE, Android 4.1.2 Jelly Bean, and Facebook Home.

It will come with 25GB Dropbox storage as standard free for the first two years.  

Facebook Home will bring the experience of Facebook friends to the home and lockscreen of Android through Cover Flow. There are no gestures to see the content flowing from your Facebook friends, it's simply just loaded in the background when the handset is sleeping. You can even comment and interact from Home.

"What would it look like if our phones were built around people and not apps?" Facebook's Mark Zuckerburg said when discussing Home. "We have our phones with us all the time. We want to know what's going around with people around us."
