I was bored so decided to open my N3 to have look inside.
For the original photo where you can see the IC markings etc. (click on raw)

As you can see there is no shielding on the Ingenic ic and a coil on the left has a bit of ferrite broken off.
Braver man than I, mine isn't coming apart unless something tragic happens and it breaks that way.
