Replace back of 3G S (UK)

[MoodyM]

Can someone tell me how, where and how much to get the back (white) of my 3G S replaced? It's all cracked and scratched.

Cheers (I'm in the UK by the way)

buy a junked or water damaged phone and switch them. all the internal components of the 3GS are attached to the back.
