Facebook today announced the introduction of its mobile platform. The purpose of the project is to provide a social environment for mobile devices that will eventually mirror the company’s dominant Web-based platform. The initial mobile platform involves a number of projects across a variety of mobile operating systems — including iOS, Android and BlackBerry — and it will allow developers to more easily expand their Facebook products beyond the desktop environment.

Platform announcements made today include:

•Single Sign-On — quick easy log-ins from mobile apps on mobile devices
•Location APIs — allows any mobile app to access Facebook location services
•Deals Platform — location-based platform for local businesses to offer deals to nearby Facebook users

Facebook is updating its Android product immediately to include support for Single Sign-On and other new features, and its iOS offering will be updated next week.
