For those that say this is "stealing", get freaking real. You're already paying to have data service with AT&T with your iPhone (with a monthly inflated price I might add since you're required to carry a voice plan as well), and they want you to pay for it AGAIN just because you use a different device?? It's a ripoff.
That would be like paying saparetly for your laptop & your desktop on your home network.
