CDMA (Code Division Multiple Access) and WCDMA (Wideband Code-Division Multiple Access) are two technologies used in the mobile world for radio access... UMTS uses WCDMA....

About the Z1010 and Europe's WCDMA. Japan uses WCDMA 2100, is Eurpope going to use the same or use 900 and 1800. I was wondering because in order to work in Japan, The z1010 would have to be dual mode (GSM/WCDMA) and triband (900/1800/2100),. what do you think?

900 and 1800 is for GSM only... UMTS in Europe will use frequencies around 2000MHz (here in Sweden 1900-2100MHz is reserved for UMTS).. so it's WCDMA 2100 here as well..

that's what I thought, its interesting how things are marketed in words that people understand, even if not technically correct. I have heard that its going to take ahile for MMS to really catch on until the menu commands are better understood by people as a whole
