Fresh off ending Twitter integration, Instagram (NASDAQ:FB) has revamped its iOS and Android apps. The apps' camera and image-viewing features have been overhauled, and a new filter and Foursquare data have been added. Sterne Agee recently argued Facebook is finally gearing up to monetize Instagram, which now has 40M+ monthly active users who connect via Facebook. Update: As expected, Twitter has updated its mobile apps to include support for Instagram-like photo filters.
