Yeah. I'm not happy either I have 4.5.77. Thought moving to .101 would help till I saw your post...
Mine get to the point of "loading favorites" then the phone resets. It works up to that point because if I have sling player running on my laptop, it tells me the sling box is in use.
Back to the waiting game I guess.
I am thinking of switching to a Curve 8330. Anyone have any luck with that BB with the sling player?
Upgraded to .101 jsut to see if I would get any closer to getting the slingplayer to work. It now get past the "loading favorited" then resets the phone when "optimizing" shows up. Tried a bunhc of settings, but nothing works. Its still a no go on my VZW 8830 gerrr!!
