Ok, so I love this phone to death, short of not being a flip phone its by far one of the best phones out STILL. Although the top right navigation button (the button furthest to the top and furthest to the right) has had its days of working and not working it currently doesnt work at all. I've even had to change my shortcut function on that button and move my calculator shortcut over to the GOTO menu (nokia users will understand what I'm talking about). Any quick fixes or advice on what to do before I call up Nokia? I've owned this phone just over a year and have tried everything short of operating on the phone at this point including cleaning the hell out of the shell of the phone. Thanks in advance.
