Bluetooth DUN (dial-up) profile on BGB203 and LPC2138

I’d like to access the Internet using the DUN Bluetooth profile and a cell phone. The platform is the BGB203 BT device on an LPC2138 processor.

From the docs, I see that DUN is not supported by the BGB203. Can this restriction be overcome by using the SPP (serial port) profile and software? Has anyone done this on an ARM7 and the BGB203?

Thanks
