Sprint Android Worldphone

If it does, it would likely be a CSIM slot (CSIM = R-UIM's successor... a superset of GSM SIM, and optional subset of UMTS USIM). All that means in terms of global roaming is that if Sprint gives us our Epic4G phones with a CSIM in them, you MIGHT able to use your CSIM in a GSM phone in a foreign country to make voice calls, send/receive text messages, and use GPRS (but not UMTS... that requires a USIM, which a Sprint CSIM *could*, but probably *wouldn't* be), have that phone ring when someone calls your Sprint number, and get raped by the roaming charges.

The immediate advantage of having a CSIM slot in the Epic4G would be the ability to buy a second one to use for kernel development purposes or experimentation, and switch between them at will without having to pay Sprint ~$20/month for a second line/number sharing the same minute pool. Though knowing Sprint, if there's a way for them to semi-immutably associate a specific CSIM card with a specific phone and make the whole thing moot, I'm sure they'll find a way to do it.
