Wideband-CDMA. It the 3G upgrade for GSM. It also goes by the names UMTS and 3GSM. But it's based on CDMA technology.

The traditional CDMA 3G upgrade is which Verizon will be following is CDMA EV-DO and enventually CDMA EV-DV.

Raulr,
Would this WCDMA phone work with Verizon's CDMA system and their upcoming systems you mentioned?

No. WCDMA and CDMA are totally different and incompatible.

Don't let the name fool you. Basically, if there are 20 major components of a standard like this, WCDMA and CDMA share only one of them. Unfortunately, it just happens to be the one included in the name, which causes a lot of confusion.

That's a vast oversimplification, but you get the idea. WCDMA has more in common with GSM than with CDMA, although really it's very different from both.
