It looks like Slacker & RIM are also giving away 2,500 free monthly subscriptions to Slacker Radio Plus on their MySpace page. This is limited to the first 2,500 people who sign up at this link. Slacker Radio Plus is practically the same as the basic radio service plus unlimited song skips, unlimited song requests, & no advertisements… I know it is only a 1 month subscription but it is free and free is usually good. 🙂
Sign up at this link (or this link and click the Apps for BlackBerry tab) and scroll down to where it says Slacker and click the “Get It Now” button and fill out their form. Can’t promise you it will work but it should.
