iPhone disassembly guides (first generation)

Anandtech did a very nice disassembly of their iPhone with many high resolution pictures.
EE Times Online has an article with some very high resolution images of the internal parts of the iPhone that labels some of the chips and describes them.
ifixit has a disassembly guide for the iPhone.
Think Secret has a disassembly guide as well.

Now wouldn't it be nice if we could all do this?
