I read the thread on "HOWTO: Use BlackBerry As Modem For Laptop!"
Unfortunatelly I wasn't able to connect with my Powerbook because I couldn't find a driver script.

My Hardware:
Powerbook G4 17"
Blackberry 7290
Software:
PocketMacBlackberry


I was able to connect my Sony Ericson t681 trough Bluetooth and I was expecting to do the same with my new BB.
