I dont have a external charger yet.

The box and phone has id's that claim to be made in Finland and after research it sounds like some N900's were made in Finland but I believe the bulk were made in South Korea.

I dont have firmware and not sure completely on flashing but the phone doesnt respond when having battery installed and plugging the usb cable in while holding the U key.

outside of tearing into this phone I dont believe there is much difference from a fake and real deal externally.
