I just upgraded to Blackberyy OS 5.0 and slinbix mobile won't work. It starts the connection process but gets stuck "optimizing." Slingbox worked fine with OS 4.6. I am able to connect to my Slinbox on my laptop fine. Slingbox support just threw up their hands (after charging me $30), saying it must be related to security settings on my BES network. OS 5.0 and slinbix obiously are not working well together. I am desperate for any fix.
