Slacker created a bit of buzz for their radio application for BlackBerry during CTIA but since then, the relatively popular internet radio provider has been extremely quiet. Now that CES is here however, the company has gone ahead and officially announced the launch of Slacker Radio for BlackBerry. With 100 stations categorized by genre and over 10,000 artist stations, Slacker also allows users to create their own stations which other users can listen to. Album reviews, artist bios and cover art are also tightly integrated into the program. Streaming radio for mobile devices is quickly becoming a crowded field but the major benefit of Slacker is that it allows users to store their favorite stations on a memory card which Slacker claims increases battery performance up to five times (when played back) in comparison to a constant-stream of music. For now BlackBerry users who want to try out Slacker must live in the US (it seems you can bypass this by entering any valid US zip code though) and have a device running OS 4.3 and up. The Storm is currently not supported but will be sometime in the near future when an update is released.
