  Some tech explanation:

  Both Verizon and Sprint are CDMA carriers.  T-Mobile, Cingular/AT&T,
and pretty much every other carrier in the world uses GSM.  Most of
the planet uses GSM.  It's only in the US that the idea of wholly
incompatible cell phone networks is accepted.  Everywhere else, you
can buy a phone from any vendor, a SIM from any carrier, and swap them
around at will.  You can generally roam anywhere in the world that has
coverage, too.

  There are CDMA towers outside North America, but they are fewer and
further between, and roaming agreements have to be negotiated on a
per-carrier basis.  So if you're traveling internationally, GSM is the
way to go.  Of course, GSM coverage in the US isn't as good as CDMA,
overall.

  Verizon's solution for us was a hybrid phone (BlackBerry 8830 World
Edition) which had two radios and two service accounts.  One for CDMA
in the US, and one for GSM everywhere else.  Crude, and still more
expensive, but that, at least, did work.
