Looking at their map, it's highly misleading, implying there's CDMA 3G coverage in a bunch of places where there is no, or minimal coverage. (They're a trade body promoting CDMA -- what would you do in their shoes?)

CDMA2000 aka EV-DO isn't compatible with W-CDMA, aka UMTS -- the 3G standard used just about everywhere -- and has about 10% of the market worldwide:

Here's a list of CDMA2000 operators. You'll notice a lot in the Americas, especially the USA, plus others scattered elsewhere:

And here's the giant table of UMTS (aka W-CDMA) operators worldwide:

If you're American and don't have a passport, then by all means get a Verizon iPhone 4. But if you expect to travel widely it'd be much more sensible to get a GSM/UMTS iPhone 4, even if it means putting up with AT&T at home. (More sensibly, buy an unlocked one from Apple on a trip to, say, the UK or Ireland: claim back the VAT and buy a micro-SIM on the network of your choice and you're golden.)

I would either tell the truth or quit the job. I take my professional code very seriously.

Very misleading. It highlights Ireland as a CDMA country (there's a trial apparently) However if you had a CDMA mobile phone, it won't work in Ireland.
