Haben,
It's less that I like T-Mobile and more that I cannot stand AT&T.
Also, AT&T will not unlock your phone at contract termination. They
could do it--Apple gives them the means. But they won't do it.
There is undoubtedly going to be a lawsuit against Apple and AT&T
over this practice of refusing to unlock phones at end of contract
period. There is a ready and waiting class of people whose two-year
contracts will expire at the end of the month.
Probably the best network in the United States is Verizon, but
they're also the least approachable for using "standard" equipment
that works in other countries because they use CDMA.
