Hi all, just to let everyone know:
I bought a replacement LCD screen from eBay (�30 including postage) as mine was scratched quite badly.
The seller included 2 tools, a Torx T6, and a plastic prying tool, to remove the case.
It took me about 15-20 mins to replace the screen (reasonably easy) and it functions perfectly, my N95 looks brand new again!
And, as an added bonus, I fixed the wobbly slider too.
