The Kyocera S2100 is Virgin Mobile's version of the Kyocera Luno S2100 for Cricket. It's available for $19.99 with the carrier's no-contract PayLo service.
The S2100 sports almost the same design as its Luno sibling, though instead of a wild purple color scheme it comes in a humbler gray skin. The flip phone has rounded edges, and the 1-inch color external display will let you check caller ID and the time without opening the phone. It measures 3.7 inches long by 1.9 inches wide by 0.7 inch deep and weighs 3 ounces.
Inside you'll find a 1.8-inch color display and a standard alphanumeric keypad. Features include Bluetooth 2.1, an Opera Mini Web browser, a VGA camera with 5x digital zoom, voice commands and dialing, personal organizer tools, messaging and e-mail, a speakerphone, a 500-contact phone book, and USB syncing.
