There's a massive market of people out there whose iPhones will never talk to AT&T ; the rest of the world. I think drilling down on the US carrier is a bit shortsighted in a proper review.
There are many sites that cover gadgets and their global hit. What I was doing here was talking about my own personal experience, which I believe is fair. Not everyone shares the same experience, and there are many outlets to share those viewpoints. But here in the US, AT&T is a major problem, and it has been such a bad problem, it has contributed greatly to my looking for an alternative.
