Well, it actually takes up far more than one call, as do most EDGE data transfers. It's not unusual for a carrier to limit any particular device to 4 download timeslots and 1 upload, even when they are capable of more.

So really, when compared to a normal transfer, the extra timeslot taken up by the voice call isn't much.

Personally, I'd be happy with 3+1 and voice. (that would limit you to about 170Kbps downstream in ideal conditions, or 100 more realistically)

The feature is called dual transfer mode, btw.

Edited to add: And having just looked it up, N900 supports it.
