I bought Slingplayer for Mobile Android last December (2010) when I bought my HTC EVO. Worked great without problems.
However, I did have to do a hard reset yesterday because of a problem with my google apps.
It erased the Slingplayer app. Now, the only way to get it back is thru the marketplace, and it looks like I have to pay the $30 again?
Say it isn't so!
