The Beta version of BlackBerry Radio is going out today (Feb. 3) to some "Beta Zone" members, to gain experience for this long-awaited feature of RIM-made smartphones. cnet says this app "doesn't intend to compete with existing standalone radio apps." Instead, it takes advantage of existing programs and services, including those from partners such as Clear Channel's iHeartRadio, Canada's Corus, and the pureplay Slacker Radio. There's no firm date yet for the wide release of BlackBerry radio to all users. See RIM's own blogpost and sign up for the Beta Zone here.
