It's a Nokia 6300, which I went to grain pains to find about a month ago. Even though it's an old model the handset was never used before so in good nick.
The other night I was using my phone at about 2am, worked fine although it was a bit low on battery. Put it down next to the bed and went to sleep. When I woke up the next day I could hear it double that beep it does when it's low on battery, but I ignored it for a while cuz I couldn't remember where it was. Then I found it and it was dead, so I plugged it in and the screen was blank. It "lights up black" if you get what I mean, i.e. the backlight works but the screen is still blank.
The phone itself works, as I can put in my PIN and make/receive calls and stuff, but have to do it all blind.
Other than ALIENS, what the hell could have caused this? Reminds me of all the headphones I had that would break for no reason.
