This is going to cost Samsung a bundle. Samsung announces that they teamed with singer Beyoncé Knowles (an 11 time Grammy Winner) to promote the Samsung Ultra Music F300 mobile phone.

Beyoncé will participate in TV commercials, advertisements, global concert tours, and other co-promotional activities with Samsung.
Samsung's Ultra Music TV commercial, starring Beyoncé, will kick off the campaign globally in April, starting from Europe and CIS and expanding to other countries where Samsung Ultra Music phones are available.
Ultra Music mobile users will have exclusive access to Beyoncé's latest hit "Irreplaceable," which comes embedded in their mobile phones.

Samsung showed the thin dual face music phone F300 already at the CES 2007. With Beyonce on board Samsung is all set to roll out their new music phone in style and glamour world-wide.
The Samsung F300 features a digital power amp and offers a dedicated music user interface. Other features of the F300 include stereo FM radio, Quick PC Sync function, 2.0 mega-pixel camera, 2.1 inch screen, 100MB internal memory, Multi-Format Music Support (MP3,AAC,AAC+,e-AAC+,WMA), Multi-Format Video Support (MPEG4,H.263) and microSD slot.
Measurements of the F300 are 103.5 x 44 x 9.4mm.
