Social user experience with the Facebook Phone by Sachendra Yadav,

There are quite a few rumors flying around about Facebook and HTC teaming up to build a new “social” smartphone named “Buffy” with Facebook services deeply integrated in a modified version of Android.

Facebook has declined to comment on the rumors stating:

"Our mobile strategy is simple: We think every mobile device is better if it is deeply social. We’re working across the entire mobile industry; with operators, hardware manufacturers, OS providers, and application developers to bring powerful social experiences to more people around the world."

Apple and Microsoft have already announced a tight integration of Twitter in their mobile platforms. Google is building its own version of Facebook with Plus, which is bound to be deeply integrated in Android in the days to come and could be a serious threat to Facebook.
