CDMA is used by Verizon and Sprint. That technology only works in the USA. It doesn't use sim cards, so upgrading can be a little more difficult.
GSM is used by AT&T and T-Mobile. The technology works world-wide. They use sim cards making it easier for upgrading your phone. On BIG upside of GSM is that you can talk and surf the web at the same time.**
** Ex. You are using headphones for the call and you need to check something on the web, you can then use data (web, navigation, etc.) while the phone call is going on.
