I'm finally considering getting a mobile. Normally I borrow it from her indoors, but she's more often than not, well, outdoors. I only need a PAYG job with Orange, but I have no idea where to buy one (apart from those high street shops, which I assume to phones are like PC World for computers). I want to spend as little as possible but get something fairly small and light. It does not need to have an inbuilt torch, PDA, MP3 or anything. Just a basic address book and easy to use UI. What to get and where to get it?
