Sprint Data?

Can this be for real?

“Because of the technology that Sprint uses, you cannot do simultaneous voice and data. With AT&T’s GSM network, you can do that. If you receive a call on that CDMA network, however, while you’re in the middle of a data session, you’d have to drop the data session,” he said.

Do you really loose your data if on a voice call even on their new network? thats just stupid.
