what makes you think they won't be using them any time soon? here is a

when phones transitioned from credit card sized sims to the current

t-mobile is only too happy to support the iphone.

which means it's *not* exclusive. all they need to do is distribute the
new sims and they have three months in which to do that.
at&t has had 8 months and can't figure out how to offer tethering.
t-mobile should be able to get a bunch of sims in that time to their
stores. instant new revenue.

and at&t now sim-locks pay as you go phones. the sim can be removed,
but it won't work in any other phone, at least for 6 months or whatever
the time period is.
