GPRS devices can have single mode (only GPRS/EGPRS) or dual mode (both GSM voice and GPRS data) capability. The GPRS system was modified using EDGE technology to increase the 171.2 kbps GPRS maximum data transmission rate to 474 kbps EGPRS data transmission rate.

Though it's been a while since I've worked strickly wireless communications, it goes something like this. While GPRS/EDGE are typically used for data only, they
can be used for voice. But since GPRS/EDGE transmissions travel on modified GSM carriers, techincally you are both right?
I don't think voice travels over GPRS, but with the higher speeds of EDGE you can get more options for voice communications over the EDGE network, which is basically a software upgrade running on top of the GSM network... if I understand it right.
