AT&T sold out of its entire stock of the new iPhone in one day with the largest online sales in the history of AT&T. It now appears that more phones will not be available for a couple of weeks. Phones can still be ordered from Apple. If this summer is anything like that last three summers of iPhone releases, there will be shortages until early fall. The new phone is a major upgrade from the previous three models, with many new features, including a much faster processor, multi-tasking, a high resolution backside camera, a front-facing video camera, and a very high resolution screen.
