Sorry Grayson. Not trying to be difficult. But I thought the majority of iPads in the USA were UNLOCKED by default.
The key is ... finding another carrier. And, I believe that is not an option - right now - here in the USA (well, and get true 3G speed...). Outside the US, it's a different matter, which is why people can buy the AT&T version iPad and take it out of the US.
