I am a bit mixed up in the following :

1- A mobile with Cellular Network as GSM & UTM means it has 3G also . Right?
2- What does it mean that a mobile has a Cellular Network which is CDMA only ? GSM is not written in its specs ! Like the curve 8930.
3- I assume ofcourse that it works also as a mobile on GSM. Right ?
4- What is the difference between WCDMA and CDMA ?

Thanks in advance.

GSM UMTS = 3G

CDMA = only works on CDMA carriers like verizon/sprint

No, CDMA ONLY works only on CDMA networks.

CDMA and GSM bands means it works on CDMA carriers, and GSM carriers abroad.
GSM is the network type most commonly found in the world. Only some countires operate a CDMA network.
Therefore, a CDMA AND GSM phone can work worldwide.
CDMA only can only work on the CDMA carrier is belongs to.

Not sure about WCDMA and CDMA.

Also there is no 8930 released currently.

I believe WCDMA is a more advanced version of CDMA (able to handle a greater bandwidth perhaps)? I'm not too sure on the technical details though.
