I'm very attached to my mobile.

I've had my Nokia handset for so long that the battery only lasts for about a day now - but it's an old trusted friend and it's never let me down.

Even though it's at least four years old, the little beauty contains an electronic compass, a torch, a thermometer... it even has a spirit level Incorporated into the frame.

The camera's a bit rubbish - and the text memory is tiny - but I got it free with a contract, it's helped me escape from a forest and put up a mean set of DIY shelves, and I'm not getting rid of it yet...
