Not long after the release of the iPhone, I pleaded for a version of Slacker for the device. The application has arrived but, unfortunately without the feature that motivated me to want it — offline listening. According to Slacker, implementing offline caching of Slacker radio stations of the iPhone would require significantly more development. However, the feature is available today for Blackberry Bold users and some have got it working on the Storm even though an updated version officially supporting the touchscreen Blackberry is in the works..
While there are a number of fine Internet radio applications from Pandora, FineTune, last.fm, Deezer and others already for the iPhone, the Slacker Radio application will at least allow users of the service to access their favorite channels. Slacker has certainly been belying its name, churning out versions of its service that runs on the new Audiovox Internet radio and Sony Bravias, but those are home products that have limited need for offline access the iPhone version could really use.
