The Nokia N8 hit the shelves less a few days ago but the N8 got a disassembly treatment. The metal-clad handset has been given a rating of (8 out of 10) for easiness of repair. Unless you need to replace the glass over the display you can tear the Nokia N8 flagship apart with nothing but a set of Torx screwdrivers.
And you would only need one such screwdriver to take out the standard BL-4D Nokia battery. Its by far not that hard to change, despite the Finnish company claiming that it is not user-replaceable. Still this will probably void your warranty so you might do better taking your N8 to a Nokia service center if needed.
