On your first question, I couldn't say if the cause is something inherent
in GSM+GPRS, a chipset limitation, something that could be addressed in its
firmware, or simply gsm software support. Hopefully one of the latter two,
right? :)
As to the second, yes that's pretty much the situation. As I understand
it, there are also limitations on simultaneous use of GSM and Wifi as well
as Wifi and Bluetooth. (not inability, just limits)
If you're sitting on a solid internet connection, IMHO VOIP would be better
anyway. :)
