Slacker has announced a version of it’s free internet radio app for the smartphone, with 100 expert-programmed Slacker stations, over 10,000 artist stations or tons of custom stations. You can even listen to music without a network connection using Slacker’s station caching, which is exclusive to BlackBerry devices

It lets you store your favorite stations on a memory card instead of streaming them over the network connection you’re using. That way you have access to them even when there’s no signal. Slacker claims that it will also reduce battery consumption by as much as 5x.

The free download will give you artist bios, album reviews and artwork in both portrait and landscape interfaces.
