Version 3 does work for the blackberry, here's the link:
MicroSky v3 for Blackberry
Three questions, tbdiscovery:
1. Are you using v3 for blackberry (the one linked above)?
2. Have you registered on the MicroSky site, and included your login information in the settings?
3. Do you have other java apps installed that can access the internet (like Google Maps, Opera Mini, etc.)?
peace,
sam
