After two years my Nokia E70 showed first signs of fatigue. In the end the click of the 5 way stick did not work anymore. I assumed dust as cause and decided to open the phone. Opening it was a success although the stick still does not work. Despite that, if anyone wants to open his E70 there are some pictures I made at flickr. Click the image to see them.
I guess the micro switch is giving in… and I guess mobile phones are not meant to last for more than 2 years as that is as long as the contracts last
