Sprint hopes to maintain a competitive edge with its latest handset, the Sanyo Katana Eclipse X, which combines the One Click user interface with the thin/flip style of the Katana series.

One Click allows users to personalize their home screen and organize features such as text messaging, Google search, Sprint Navigation, email, favorite Web sites, music and call log.

The Katana Eclipse X includes Sprint TV with live and on-demand programming, Sprint Music Store with full-length songs, Sprint Radio with more than 150 channels and a built-in MP3 player with microSD card slot supporting up to 8GB (256 MB card included).

Additional features include a built-in speakerphone, stereo Bluetooth technology, external music navigation controls and a 1.3-megapixel camera with 12x zoom and video camcorder.

The Sanyo Katana Eclipse X is available in Sprint retail channels and online for $99.99 with a two-year contract and $50 mail-in rebate.
