It's no small irritation that the N900 doesn't work on AT&T's US 3G network due to the frequency problems. I've been trying to determine exactly what chip the N900 uses for it's cell transceiver chip without actually tearing down my unit. After a lot of research I was able to find this page:

But of course that's the one thing they don't know. Has anyone either taken a nice NIGH RES photo of the back of the circuit board (the techblog.gr video is useless for this, as is the N900 service manual I found) or know the part numbers?
