Just a few hours after launching the new Timeline profile design globally, Facebook is debuting the new feature on Android and m.facebook.com. The smaller screen keeps the mobile timeline constrained to a single column instead of the web version's dual column setup, but you'll find a lot that's similar here. Now, when clicking through to a friend, you can scroll through their history (or your own) by days, weeks, months, and years. Images feature much more prominently in the new Android app, and swiping left or right moves you through maps, photos, subscribers and more. While Timeline is coming to iOS soon, according to Facebook, there's no word on a release date. For now, iOS users will have to use the mobile website.
