I've just been told I sent an sms saying "f". That's the message. Funny how I didn't think that I sent it. But it would explain the beeps I've been hearing from my phone as I sit on it: without the key lock on it.... oops. Who else have I sent strange messages to?
In other news my earphones are well and truly dead. Well, they still work. There's just a bonus buzzing sound that can be heard only when they are in use :)
