Digit Wireless, which teased us the past couple years with its Fastap keyboard, has finally brought the technology to the United States. Alltel yesterday introduced the LG AX490, the first cell phone from a U.S. carrier equipped with the Digit's alphanumeric keypad technology. Set in the midst of the AX490's usual number keys are small, round buttons for each letter of the alphabet. Designed for quicker and easier messaging, the raised buttons essentially give users a full alpha keyboard. The AX490 flip phone also comes with a VGA camera, a speakerphone, and Bluetooth, while the price should be $59 with a two-year contract.
