Well, I found this app on the internet that says you can call anyone in north america using internet explorer and a headset. Simple sign up page in the beginning, and requires a email validate. http://labs.jaduka.com/earthcaller Works okay, calls are pretty good. Its called "earthcaller" on that site I believe. Just called some friends this thing is cool and is so needed in the days of wifi and all that. Now someone let me know where I can find a cell phone one?
