Slacker Radio is a popular radio service that has done really well on the Windows Mobile platform and all indications are that success is carrying over to Windows Phone 7 (we'll have a review up shortly).

To help celebrate the launch of Windows Phone 7, Slacker Radio and WPCentral are going to giveaway six, three-month subscriptions to the radio service. All you've got to do is head on over to the WPCentral Forums and, in this discussion, let us know what you would like to see Microsoft include in the first Windows Phone 7 update.

We'll let the conversation run through 7:00pm CST on Thursday, November 18, 2010.  We'll then randomly select six posts as winners. You do have to be a registered member and that simple process can be found here.

So, head on over to the forums and tell us what you think and good luck to everyone.
