If you have recently upgraded to app 8.351 you may be having the phone problems we discussed in that thread.
I too have a Blackberry (albeit an "ancient" 8100). After initially upgrading"(?) to app 8.351, everything was working fine, the phonebook transfered both names and numbers etc, etc. Then suddenly all I got was "This function is not supported on this device" whenever I tried to use anything associated with bluetooth.
I re-installed app 8.302 and all has been well since. Please note however that I documented the fact that my phonebook didn't transfer in its entirety. SOME numbers transfered while no names transfered. At least the bluetooth now works and I can at least look up the needed numbers off the phonebook in my phone itself.
Hope this helps.
