Bank of America claims to be the leading mobile banking service, with more than 1.8 million people accessing it via their mobile devices. The Bank of America iPhone app lets you do all your banking via your iPhone or iPod Touch. A neat feature of the most recent release is that with a touch of a button, you can use the location awareness of your device to find the nearest ATM or banking center automatically — without entering your address or Zip Code. It also has a faster, easer-to-use interface. You can use your iPhone to check your balance, pay bills, and transfer funds.
