Windows Mobile: check. Palm OS: check. S60: yep. So what's the giant, gaping hole left in Sling's coverage of mobile clients? BlackBerry, of course, and the company has finally confirmed what we already sorta knew -- that a SlingPlayer Mobile for BlackBerry is officially in the works. Sling will be demonstrating its latest client at CES on a Pearl 8120, utilizing its WiFi connection (though 3G will work just as well) to stream down an endless barrage of mind-numbing content from the Slingbox of your choice. Look for it to show up on a BlackBerry near you "later this year" for a shade under $30. Hop on over to Engadget for a quick hands-on with the goods!
