I received this from HTC about the USCellular updated ROM (below).
If anyone can figure out the needed mods to make the updated ROM work with USCellular a case of your favorite beverage is on me.
Knowing USCell over the last several years they will NOT be releasing an update. They too marketed this phone as having GPS and I point that out to them when I contact them.
