Facebook admitted during its mobile event today that the app for Android devices has been lagging behind other clients and has already made a push to correct that with a new version, 1.4, now available on the Android Market. Not much has changed, but the list of fixes indicates it now supports check-ins with Places, Groups and some much needed improvements to notifications. Check out the gallery for a few screens of the new functions in action or snag the QR code after the break.
Update: It looks like the iPhone app is getting an update as well. Unfortunately, some folks are having trouble downloading it. Let us know how it goes for you.
