HSDPA/UMTS (for GSM carriers such as AT&T) is a 3G wireless networking topology that does support simultaneous voice and data.
There's no such thing as "true 3G".
So basically 3G is just a marketing term and has no official standard? Then EDGE would also qualify as 3G which confuses me even more because the original iPhone would then qualify as 3G.
