Free internet on nook

I just got my September issue of Popular Science in the mail today and they had a nice article about the nook. They discuss how to hack it to access the android system and install apps on it. I am not too familiar with the nook and was wondering if anyone had tried this yet.

The nook 3G's 3G connection is free... right?

If so, couldn't I hack the nook to Android and install a web browser and use the 3G as my connection. I'm sure webpages wouldn't load nice on the e-ink display, but I would just use it for email, news, and basic things.

Do you think this is possible?

Thanks

I think that the webbrowser it comes with only uses wifi
