I have been finding a lot of errors while trying to see LightStreamer demos using a Blackberry with OS 4.6 and 5.0. The demos won' work. They work only for BB OS 6.0.
I tried looking at the BlackBerry application demo and there is a "connection refused" error, and I can't make it run, even with OS 6.0.

Can you supply more information about BlackBerry OS Issues?

Thanks in advance.
