The Handspring docs aren't great, as Thomas Maeder pointed out.  However I
was told that there'd be more docs about the Treo going up soon, once the
GPRS stuff is finalised.

To the problem in hand...

Not sure how to get the IMSI via Treo APIs... However, the AT command set
provides AT+CIMI, which returns the IMSI.  Anyone know of a way to send AT
commands at the SIM?  Failing that.. can you create a loopback with the IR
port so you can effectively send AT commands to yourself?
