Slacker Personal Radio 2.0 is now in the iTunes app store, along with its great new local caching feature (hello new AT&T capped data plans!), and to celebrate Slacker wants to give away five (5) one-year subscriptions to their premium Slacker Radio Plus service (and they're throwing in five (5) 3-month subscriptions for runners-up as well).
It'll be the perfect thing to run on a new iPhone -- and oh, yeah: TiPb's giving away an iPhone 4 as well.
If you want to win, download the Slacker Personal Radio app from iTunes, try it out, and then leave a reply below and tell us what music you're caching on your iPhone.
