How does CDMA work

[Wicked1]

One other drawback to Verizon and Sprint, is their phones can not be used on other networks, unlike the iPhone on GSM.

I can sell an iphone 4 unlocked to anyone in the world, a CDMA phone can only be used by the carrier it was built for, so there is another drawback to CDMA.

You mean world wide except the United States. It will not allow you to use a US SIM Card inside of it at all. Try putting in an ATT SIM = BIG ERROR.
