Hi,

the current release is not completely compatible with blackberry devices.

we've added such compatibility for our next release.
You can check a preview of such release here: http://www.lightstreamer.com/whatsNe...w-release.html

The new version of the sdk also contains a blackberry example. Check it out as it shows how you'll need to use the library to work with blackberry devices.

let us know if you have any issue.
