Yes, they're late to the game, but Sling Media has finally released a SlingPlayer Mobile beta for all you Palm OS fans out there. You'll need a Treo 700p, 680, 650, or a Palm TX to run the beta, but it'll be nice to join the ever-growing crowd of mobile Slingers. Testing will start next week with a second wave of testers rolling out the following week. As for all you RIM owners out there, sit tight. Your ship may be coming soon.
