Update: 4.7.0.151 is a #*@%!^$ MIRACLE!
Ever since moving out here about two months ago, I've barely been able to use my phone at all because the signal was so bad. Even sitting outside I could barely hold a conversation because most of the time whoever I was talking to couldn't hear me or I couldn't hear them. Every other call got dropped. I tried a few different OS versions, including hybrids, and nothing solved the problem.
Today, though, I spent an hour on the phone walking all over my house and the call didn't break up a single time. Even in spots that were known dead zones it was totally fine. Neither my friend nor I could believe it. lol
This one's a keeper!
