Well, I'm going to agree with everyone who's said "get a new one", as mine (new on Monday 7th December, delivered from Mobilephonesdirect.co.uk) has been randomly rebooting all week and last night it made its terminal reboot - now I have a rather boring black Nokia paperweight! What's more irritating is that nobody at Nokia UK or MPD seems to work on the weekend so I've got to wait til Monday to sort out a replacement :-(
