Not relevant for people who switch phone in two years, but AT&T's phone unlocking at the end of the contract or with account charges taken care of, is pretty neat.

If a Verizon account has been in good standing for at least 60 days, supposedly they'll unlock your device: http://news.cnet.com/8301-30686_3-57361283-266/will-verizon-...

Only for international use. Domestic use is still locked to Verizon.
