I'm sorry, I was specifically talking about CDMA phones, I thought the OP meant just Sprint CDMA phones, not iDEN, sorry about that.
Actually reading more up on it, both iDEN, and GSM are based on a technology called TDMA. GSM is actually the basis for iDEN. So that would explain why iDEN phones use SIM cards. There is a purpose, it isn't just there for contacts and messages.
