The iPhone blog says that AT&T is going to start contacting iPhone owners who aren’t using an official iPhone data plan and force them to sign up for one. The crackdown supposedly starts tomorrow in the Atlanta and Austin markets, and expands nationwide by the end of the month.

If you’re one of those people who managed to get by without an iPhone data plan all this time, let us know if you hear from AT&T over the next few weeks.
