Whoa! Finally, Apple fully delivers on this iSynch Bluetooth iCal thing! In June, I could Bluetooth (Bluetooth is a verb isn't it?) between my P800 and Powerbook but still couldn't Synch to my calendar. I just downloaded the new iSynch and iCal updates. It will take me a little while to test it, but they are saying very clearly that P800 works now. Other devices are also newly supported, so check the links.
