It's not 3G only. 3G only supports data transfer, not voice calls. 2G (GPRS/EDGE) supports voice calls and data, but data at a much lower speed. Therefore, in order to be 3G and make voice calls, it has to be 2G/3G. At least AT&T is thinking ahead by making 3G available through this.
you are incorrect. at&t's 3G service is for voice and data. this will work for 3G because gsm doesn't work will with this technology. their entire 3G network does voice and data. cdma carriers are the ones that doesn't use 3G for voice.
