Google just announced that AT&T customers with Android phones can now charge apps to their AT&T bills. (That's something T-Mobile customers have been able to do for a while now.) So if you have an Android smartphone on AT&T, you'll soon have an updated Market app that lets you charge apps to your bill. Huzzah.
Also, Google mentions that new app categories are live, including "Media and Video," "Music and Audio," "Business" and "Sports," among others. Look for the AT&T billing and new categories with your updated version of the Android Market app. [Google]
