Whoops, I missed this one.
Indeed CDMA and GSM are different, competing standards. Verizon and
Sprint used CDMA(PCS) for their network, and AT&T,T-Mobile, and
the REST OF THE WORLD used GSM. If a device says it has both...
All phone standards before LTE acted like they had data grafted on
after voice stuff was worked out. So as the data speeds increased
(with new technologies) the standard way that calls were handled
NEVER changed over the years. Nitpickers will say changed codecs
increased call capacity 4 and 8 fold per tower, with lower voice
quality as a result, but it was still GSM (for example).
The "G"s in 2G, 3G, 4G are arbitrary marketing speak as they are
used. They give you a feel for the speed you should feel on the
handset. Feel me? There is an actual minimum definition of 4G by
the ITU that is largely ignored in the media/marketplace.
So knowing what technology is used will just give you a range of
possible speeds. If the tower you are on has that same tech, and it
is tweaked properly, then you can get good speeds. Or if you are in
a cell that has it but is far away... Or you have to fall back to
an older and slower tech...
Wikipedia 3G and 4G, they have a great set of pages that use all the
