We mentioned earlier last week that Sprint will be launching a quartet of new phones, with the Samsung SPH-A640 among the four. Here are more details regarding this clamshell handset. The A640 boasts a hidden OLED external design and sleek lines that are pleasing to the eye. Beneath this CDMA cellphone lies a VGA camera with a self-timer, white balance, brightness controls, Push-To-Talk support, Bluetooth connectivity, speakerphone function, voice dialing, and a WAP 2.0 compatible browser. The SPH-A640 is free from the Sprint website if you sign up with a two-year service agreement.
