Having splashed out big bucks on sponsoring U2′s latest world tour, BlackBerry-maker Research In Motion is hoping to reap the rewards. Starting with something described as “The U2 Mobile album”, for which RIM has launched a teaser website.It’s light on detail and heavy on slogans (the site, obv, not the album. Although…) So it will let users “show the world what the music means to you” and “experience the tour from all angles”. Having trumpeted its commitment to music at MidemNet this year, RIM has since flattered to deceive, with many of the music apps on its BlackBerry App World store already available on other handsets. Maybe U2 can help to change that, along with Will.I.Am’s Dipdive app, which is already available.
