If I wind up getting an unlocked S2, I will be keeping my 8320 in regular rotation. I recently am doing work travel in rural VA where I am about 8 minutes outside of TMO coverage off the Interstate. All US Cellular country. I connect to the wifi at the hotel, login through their portal and I am making and receiving calls with no issue. It is a lifesaver for the rare times I have come across no coverage or very week coverage inside a building or restaurants etc.
