Master P and his son, Romeo, are reportedly on board with T-Mobile to help promote the new Sidekick LX. The angle of the campaign? To show that the Sidekick continues to be one of the most popular devices in the “urban communities”. Not only are they praising the device, they’ve also created a song about the Sidekick (entitled “Sidekick” of course) for inclusion in their next album, “Hip-Hop History”. The album is due out Sept 4th. No word on an official release on the Sidekick LX, but it would make sense from a marketing standpoint to promote both the album and the device around the same time. Our guess? Late September, early October.
