Samsung F300 for Sprint

At least one of Samsung's Ultra phones is destined for the US, an anonymous photo set has revealed. Although tentatively confirmed through an FCC filing that revealed just the skeleton of the player, the F300 (better known as the Ultra Music) was all but confirmed from images taken at a company meeting as heading to Sprint. The unique, double-faced phone will be rebadged as the M620 and support Sprint's CDMA network but should otherwise remain close in spirit to the Korean version.

The presentation didn't reveal a launch price, but did reveal an April release window, according to the source. Two mysterious phones known as the Pro 700 and 800 were also revealed but were not associated with a particular cellphone maker, with photos revealing only the ruggedized nature of the 700.
