I assume by your username; that you are using an o2 flame(?)

For your data connection there will be an interface through a COM port (as the GPRS connection is through a modem). You will need some of your own research/experimentation to find the port that responds to AT Commands. Then you can send an AT Command that drops your connection from GPRS to the bog standard GSM.

I'm sorry I'm being almost deliberately vauge here as I don't remember the exact command; also this was for a BlackBerry device - thats not much use here. For practically all mobiles, if they provide an AT interface, you may send:

AT+CLAC

and the mobile will respond with all supported AT Commands.
