>>>2. Considering placing 2 geo's at poles for complete global coverage.

Geostationary satellites have to orbit in the earth's equatorial plane, and I believe they need to be at 22,000 miles (35,000Km).
I don't see how there's any way to send a usable signal that far with a handset sized device.

It will probably take 2(or 3 or 4?) new planes of satellites in polar orbits to cover the poles.I hope someone who knows what they're talking about will give a proper analysis of what it would take to do this.

I guess its OK to be thinking about covering the polar regions and oceans, or to someday need more bandwidth :). But I'd like to hear what is happening to turn the existing constellation into part of an economically viable business.
