Samsung's US-bound F300 Ultra Music will get a rebranding on its way to Sprint, a leaked Flash demo for the cell provider has shown. The device will come to the carrier as the UpStage to reflect its unique approach to music playback: unchanged from its ITA launch last year, the handset has a large screen and touch controls on one side for media playback, and phone controls with a smaller display on the reverse face.

A 1.3-megapixel camera, a Bluetooth, and a microSD slot round out the features. The rechristened Ultra Music shoudl make its appearance at CTIA this week and will be available shortly afterwards. A full photo is available after the jump. [via Engadget]
