Brick dead again

God only knows how many times that brick has been charged up, in yet now it seems to be going down more than ever. When it was five month or less old, I carried on unplugging it, to use, to text myself everywhere I went. Couldn't go without it. In yet it's set the cat amongst the pigeons when I went on holiday with it last year, because other people wouldn't leave it to charge up, then it broke down in a french city... And now it's left with half the keypad missing - and it's all down to the abuse I've given it over the years!
