Plenty of posts right here explaining how to do it with illustrations and everything. Did the bluetooth last night along with a new keyboard. The plug for the bluetooth module becomes obvious when you drop the unit in. There is a plug on the mainboard and the jack that comes off the module literally falls right next to it when you drop the parts back together.
Be prepared for many small screws (all the same size, so thats nice), and a little prying apart, although it was not nearly as tight as I expected.
Bluetooth is a cinch. Camera is more entailed.
