Even if no one's ever bought a BlackBerry (or, for that matter, a BlockBerry) for its multimedia prowess, things are starting to get a little interesting for the rock'n'rollers over at RIM. According to the Telegraph (UK), the music download site 7Digital will be launching a service for U2's new favorite handset this September. Based around an application that will be available in BlackBerry's App World, customers will be able to download music (with "most" tracks being DRM-free) directly to their phone for 79 cents a pop. Are you excited? No? Well, RIM CEO Jim Balsillie sure is. According to the article, he believes that the market's experiencing nothing less than the "birth of digital music 2.0." What do you think?
