One of the topics on this thread was buying a phone without a contract.  I'm
not sure if it was really mentioned, but of course a phone w/o a contract is
not an unlocked phone.  In this case you are stuck with AT&T if you buy an
iPhone, you can't choose to use T-Mobile.

Are there other situations where you pay full price for a phone, but still
are required to use it with a certain carrier?  Maybe the "Google Phone"
with T-Mobile?
