For the most part, yes. Not as bad a Japan but much worse than Europe.

It can be, because unlike Europe there are several different cellular
standards used.

Almost. The standard models of phones are "customized" for the carriers to
take away features that might reduce the carrier's "income stream". This is
usually called "crippling" a phone. However, I have a couple of ex-Vodafone
handsets and they are "customized" in the same way, so this is not unique to
North America.

Maybe. They are almost all locked to the carrier that sold them. So, you
would have to get the lock removed. Also, this would only work for the
GSM
carriers. The
CDMA carriers will probably not activate another carrier's
phone.

GSM,
CDMA or
iDEN.

After you unlock a
GSM phone, yes.
CDMA and
iDEN, no.

You an I are in the minority. Most people seem happy to bind themselves to a
carrier for eternity to get a "free phone". Most carriers won't even sell
you an unsubsidized, unlocked phone. Most insist that you sign a long-term
contract no matter what but the term is more like 1 or 2 years, not 3-5. You
can get prepaid service and not worry about the contracts.

This is easy with some of the prepaid
GSM carriers and MVNOs.

What you are asking is a bit of a foreign concept in the US & Canada. 99.99%
of customers take what the carriers offer. In many cases they take the
low-grade "free phone" and move the
SIM card to the phone they bring with
them, rather than trying to explain to the carrier what they want to do.
This only works for
GSM. For
CDMA and
iDEN you are stuck with what the
carrier sells.
