For the longest time I've had intermittent connectivity with Phone-as-Modem hack using Bluetooth on my Windows XP laptop. It would connect on the first time I created the connection and then the next time it wouldn't. This has been frustrating me for over a year. I've done everything per the threads but still no luck until now!

I remembered when I had a Treo 300 there was an initialization string that you were supposed to put into your modem settings. Well as luck would have it I still had those settings saved in my notes and tried it. Guess what, no more problems!!!

So if you're still having problems try putting this into your "Extra initialization commands:" of your modem settings:

Hope this helps at least one person.
