I'm not saying you are implying it, but if anyone gets the impression that
GSM iPhones are better than CDMA iPhones because of the number of bands,
they are mistaken. In most locations, only two or three bands are used in
any given system. For instance, only two bands are used for GSM in North
America (850 & 1900) while in Europe, completely different frequencies are
employed (900 & 1800). So the only advantage the GSM iPhone has over the
"CDMA" iPhone in terms of frequencies is that it can be used in many more
countries and continents (see
http://en.wikipedia.org/wiki/GSM_frequency_bands for other continents).
In considering the two systems, there is a lot of debate over whether the
"GSM" or "CDMA" systems will provide better service. Theoretical aspects
aside, if the cellular coverage has anything to do with it, Consumer
Reports' findings, based on 58,189 survey responses from subscribers,
suggest that Verizon will clearly outperform in most major cities.

And I suspect that actual coverage area will also be greater for the
Verizon network.
