"The primary reason that the SIM was a late arrival to CDMAland is an acute manifestation of the NIH syndrome."

Really? Who could forget the disappointment and transition headaches from 5V SIMs to 3.3V sims. Why do you need a SIM in the US?

Verizon has always been able to transfer everything but my brew apps and my voice notes (oops...) between every phone I've ever activated (never the same brand twice in a row).

Eric, IS41 (the control protocol of AMPS) was born long before the SIM and the protocol that required it, GSM-MAP. In addition, European cellular manufacturers bet the farm that CDMA would die 10 years ago and their IS-41 enabled TDMA standard would carry the US torch...minus any SIM card support.

NIH doesn't justify a feature 85%+ of us don't care about.

If you dig through FCC innards pictures, Nokia CDMA phones have had SIM card slots in the board layout of their IS95 models but not included the socket assembly or a case opening for access.

"QUALCOMM never developed much of any in-house expertise in SIM technology"

Isn't ARM RUIM code available from third parties?
