I was so excited to see your post but I see that we are still all alone. I've been really busy and tried connecting using the DUN profile but phonecontrol doesn't load, and the DUN hack on the treo is far from being stable. you can get the hacked bluetooth.prc from www.shadowmite.com Give it a try and c what happens. The treo doesn't support a serial port profile except for when you hotsync, and then I'm not sure what port it uses. Any ideas?
