I have a PowerBook G4 with the D-Link bluetooth USB adaptor. My Palm TungstenT has built-in bluetooth. I followed the (wildly confusing) steps I found at both Apple's and Palm's web sites. The Powerbook and the Tungsten *can* discover each other and pair up, but when I try to sync all I get is the message: "Unable to initiate HotSync operation because the port is in use by another application." I have tried everything imaginable (to me) to fix this, but nothing works. Actually, there was a period of time when syncing did work, but then when I tried to put iSync in to the mix it stopped working again. Taking iSync out again, which would seem the obvious fix, didn't work. Anyone have success with this stuff? Steve
