Bank of America has updated its Android mobile banking app to version 3.1.120 with a completely revamped appearance and user interface. Anyone who thought the previous versions were a little heavy on the “blah” should be pleasantly surprised to find a more user-friendly experience with a clean, polished finish that's sure to please even the pickiest mobile bankers. All of the main functions remain, including support for multiple accounts, a bank and ATM locator, account transfers, and mobile bill pay, though these functions are now found in tabs on top of your account's home screen. The update also makes the app available for the first time to Bank of America customers in Washington and Idaho, who are now invited out of the mobile banking dark ages.
