Hi,
something disturbing happened yesterday evening. First the 5800 made a bit of a scary beep sound when I pressed the menu button and then the screen distorted and went black. Reboot. An hour later as I was listening to an mp3 file it all of a sudden went quiet. I then pressed the pause button and -zap-, reboot again.
Sounds like this phone has to be returned, don't you think? It's only a few weeks old.
