I agree with this. It's going to be totally re-designed. I remember reading somewhere that it's the 3rd year of a cellphone that is the toughest sell because people begin to lose interest in it. I think some AT&T person wrote this. Now, I don't know if Apple will experience this usual lull, but I'm sure they will be ready for any bump in the road
Maybe with a front-facing camera next year. AT&T has one year to beef-up its bandwidth capabilities for this, but I don't think they can do it. It may be one of those scenarios where the rest of the world gets it and we get "coming soon".
To preserve compatibility with docks and other accessories, I imagine that the port will just be added to the top, left side underneath the volume rocker, or the right side.
