I've a bud who has sub-4.7 software operating software on his phone with the same issue as you...this might be an actual question for the BlabBerry FAQ forum.
I have a BB 8800 and can't get it to work either. I'll keep messin around maybe i'll get lucky like you Slamnek. If they do respond to your email could you post your findings. Thanks!
It works great on the 9700 Bold. I can now connect via WiFi when available making it much faster than the EVDO with the 8830 I had. It is also much faster on the 3G network now available. I think I may have to actually purchase this one!
