If you’re running an Android on AT&T (c’mon, there will be more soon), check out the free app MyWireless Mobile. It allows you to pay bills, view usage data for talk, text, and web, and even lets you change plan add-ons. It is not clear at this time whether or not the app facilitates changing the base plan. Can a Backflip owner check it out and post in the comments?

Search the Market for MyWireless or check out AT&T’s dedicated page.
