I've been trying PDAnet with my 650 since I now have a bluetooth equipped laptop. I got it working once, but for some reason it seems incredibly finicky and inconsistent. Almost every time I try it, something with the verizon wireless data connection seems to fail. If i hit connect again, i get a 780 error saying the bluetooth connection could not be established. As far as I can tell, all the settings on my computer are correct, as well as on the treo. I can hotsync via bluetooth with no problem, so why wouldn't this be working? Has anyone else had trouble with pdanet? Anything I should change? I haven't tried it with the USB cable yet, but I really would like to make the BT work (especially if I'm going to pay $35 for it, which so far I'm unconvinced I will do). Again, it did work once and was quite nice, but unable to make it work since then. Thanks...
