it was posted the night before on the forums as well. before we knew it was from CES John and i were trying to find a link to a beta or something it is a great thing though, i will have secondhand knowledge from a friend sometime next week
I'm sure it'll work on any carrier when it's released. I did talk to someone at SlingMedia and they said they haven't announced any release date other than it will be this year. If I hear more from them I'll post it. For now, it's still just "in the works."
I can use my BB to tether and Sling and it's decent...a little choppy. I would think with the small display of the BB that it would be possible and not too bad. Obviously, EVDO or WiFi would be preferable. My biggest concern will be how it handles memory.
I would say probably at first. i think they will develope for the new technology before supporting the old. and i have signed up hopefully they will contact me for a beta. i can safely say i probably have access to more different devices than most people they will see lol
