BigDaddy:

Your Blackberry's won't sync because they only link to headsets via bluetooth.

The 770 is bluetooth 1.2 compliant. You have to look carefully to see what bluetooth profiles the phone supports and make sure they match up (i.e. dial-up networking, file transfer, generic access, SIM access, and serial port profiles).

Good luck. Sorry you've been having troubles. You can always wait 6 months for a better version to come out with less bugs and with more phones that support it.
