You gave yourself away mate.

For what its worth, the U.S. seems to be someway behind the U.K. when it comes to mobile phone's and calling plans. Looks to be about 5 years.
A pre-paid phone is worth having any way. As a back up. Just make certain that the minuites don't expire after, oh say, a month. As used to be the case in the UK.
