of course, not in no-service areas, my point.
But aside from that, the mobile hotspot is an interesting issue. It's not obvious that all phones/providers can do that. My current phone can do it, but Tmob was/is charging extra for the feature and somehow were able to block it apparently. I need to check that out.
Ya, that's a tricky one. But you have found an app that does that part right?
To work around the carrier tethering fees, there are a few apps out there. They seem to get figured out after a while though and then a new one shows up with another work around.
The only real solution is to root your phone. You can then use the data in your plan anyway you want. Which is how I think it should be.
