An AP report suggested today that AT$T will penalize iPhone 3G owners that do not activate their phone within 30 days.

There would be penalties for users who do not activate the iPhone in the first 30 days, AT&T said, in a move aimed at reducing the number of customers who buy an iPhone and tweak it so that they can use it on another network.

What the penalty is is a mystery so far but we’re hoping to learn a little more in the close future.
