An N900 schematic appears to be at [1]
This might not be the exact version of the schematic used to make the phone.
Revision is given as 2JH_21A on the schematic. However, the pictured PCB in the schematic is 2JH_20 - see above the third row from the right keys. A dissasembled purchased n900 showed a revision number of 2JH_21[2].
