Has anyone used those usb sim card readers to make phone calls through the pandora yet? I believe I've read something about someone using one of these usb sim card readers as a wireless modem, but they said nothing about using it to place phone calls over the pandora.
Here's some links to usb sim card readers with voice that may be able to turn your pandora into a cellphone.

Seems like it should be possible, but it just hasn't been done yet.
I guess the logical next step after getting one of these external usb modems working would be to some how implement it hardware wise into the pcb, but lets take this one step at a time.
