BTW, UTMS (3G) is also CDMA, but a different version than the 2G CDMA 2000 that was used on Bell and Telus.
No, it's not. Wideband Code Division Multiple Access is but one of several air interface standards withing the Universal Mobile Telecommunications System family. WCDMA is definitely not equal to UMTS; you can have UMTS without using WCDMA (and some carriers have).
WCDMA is also not the same as CDMA. In fact, they're not even the same technology. WCDMA and CDMA2000 are air interface standards while CDMA is just a channel access method. WCDMA uses CDMA, but it is not equal to CDMA.
So, a more accurate statement would be that some UMTS networks (including those in Canada) use an air interface standard that makes use of the same channel access method as CDMA2000 networks.
Of course, in Canada and the United States, we've come to shorten CDMA2000 to simply CDMA, and this has passed into colloquial language. In that case, we're referring to the air interface standard and not the channel access method. This is what Apple is doing in this case. If you're discussing networks from a technical standpoint, this is technically incorrect, but if you're talking about them from a consumer standpoint, this has become colloquially correct. And this is a consumer
Because of this, UMTS carriers in Canada have specifically avoided ever referring to their networks as WCDMA, using UMTS or HSPA instead. Calling them WCDMA or simply CDMA would only serve to confuse consumers.
It's a similar situation to Macs vs PCs. Technically MacBooks are just as much personal computers as Dell's Windows-based laptops, but the difference has passed into colloquial language. You can argue about it until you're blue in the face, but it won't change, it's too far engrained into our language now.
