No, Facebook did not announce their own phone, but they did reveal that their Android app is getting a refresh. The update should be available in the Android Market soon and it adds new features like places, groups, and improved notifications.
The focus of Facebook’s mobile event were several new key features for developers including single sign-on, an updated location API, and their deals platform. These new services create what Facebook calls a true horizontal platform and will allow developers to create new types of applications and experiences across all the mobile operating systems.
It looks like the update just went live so I’m going to go play with it and report on it later. What do you think of the new Facebook app for Android? What other features would you like them to add?
