V551 Bluetooth And My Mac


When I try and use bluetooth file exchange to transfer data to my phone to always seems to drop the connection.

I have a 1.25 ghz Mac mini with 512 mbs of ram and OS X Tiger
I am using an external bluetooth adapter ( Iogear GBU211)
My phone is a Motorola V551

Isync seems to work fine though

any help would be appreciated thanks
