That is strange Cuban.  My BB is running 5.0 and the streams are working well.  I think my old phone was running a late 4.5 or 4.6 and I couldn't get it to do anything with the feeds.  I swear I think alot of our problems are carrier related as well.  Not only is the BB lineup in a constant state of ....um...phlux  

, but carriers are too.  Acquiring towers here, losing them there, enabling GPS, disabling it, intermittent streaming, etc.  It's just a guess, but it seems logical.
And ditto on the offer to beta test.
