Here is how I got this combo to work (on T-Mobile):
It is very easy. I have the socket bt card, so I loaded the drivers on the ax, insert the card and use the socket "get connected" wizard. Go to the t68i, connect, bluetooth, add device. The 2 units communicate a little, click ok, type in the same password on both devices, and they are "paired"
Out of the box, the socket software adds a "dial contact" to the options when you tap and hold a contact on the ppc. This is the only function that is added by its software.
To connect to the internet, go to connections and create a new one with "bluetooth phone" as the modem. Then enter the phone number of the ISP you want to dial. I use a number from
www.freedialup.org
because my plan is not a data plan, but it does have free long distance. The numbers for that ISP are in mass, RI, and NH, but they charge nothing for the connection. So I just use minutes to connect. If you have a data plan w/ t-mobile they can give you the numbers to enter for the connection. If you need more info on this, there is a good cell phone forum at

Good Luck
