If the last update to Facebook for Android, version 1.6, brought the highly anticipated and requested feature of video uploading on addition to Pages, the latest version 1.6.1 brings even more features and improvements to the table.
There is an update available in case your Android Market didn’t notify you and it’s for Facebook. The application refresh brings improved Pages support — introduced via version 1.6 — as well as the ability to view all the Pages you Like and those you administrate. You can also post as a Page you admin and even tag Pages in status updates using the classic at (@) sign. And if this is not enough for a minor release then there are still the various bug fixes which should further improve the application.
