What do mobile phones have to do with unknown rockstars about to hit it big? Besides the fact that you can text your votes into American Idol, that is? They've got everything to do with one another, at least when it comes to corporate promotions and your chance to win a spot in the lineup of a major tour.
Samsung Mobile is sponsoring the Unsigned Battle of the Bands, with a spot on Rockstar Get a Life Tour and $7,500 cash up for grabs. You don't have to be a rockstar to win, though - Sammy is also offering five grand and a trip to see the tour in the city of your choice to one lucky fan, and a bunch of daily prizes (phones, shirts, etc), as well.
To enter, head over to Samsung Unsigned and register yourself or your band. Fans can listen to competing bands on the site and cast their votes online or via SMS. Complete rules, terms, and conditions are available on the site.
