Well, even so, replacement batteries are ten a penny. It can't be that difficult: I can still get cheap batteries for my 6150 which is about ohhh, 4, 5 years old? I get the impression that a certain 8 series phone is on the launch pad for the skip.

Think about the way you dispose of it if you do, don't just toss it in the can, get it properly reduced by an authorised disposal company. Contact Nokia and they'll help. Electronic waste is growing incrementally by around 80% per year and accelerating.
