I don't know, though, what process was used on these boards-- only that hand soldering is a royal pain on surface mount components.

after quick read on the net and checking out video tutorial it does seem like a valid option for anyone that know how to use soldiering tools and got no fear 
you seem to know fair bit about n900 Texrat any chance you could point to spare usb port with identical layout as one used in n900?
wouldn't mind ordering couple to have it ready (and hope i never need it)

Is powermat the only wireless charger company? This could work around the weak usb port for daily charging
They don't have the wireless charger available for n900 or 5800XM yet

That said, there has been no mention as to how this has been improved (just that it has), and I haven't seen any good pics of a disassembled production n900 yet.

If your n900 said/says n900 in the upper right corner, it was production.
If your n900 does not say n900 in the upper right, it is pre-production. It is extremely unlikely you would receive a pre-production unit without knowing it.
I've seen that video, but it's not clear enough to really tell whats going on RE the female usb port

also if this would happen, is this someone we could replace on our own? i know how to deal with regular electronics assembly but never had to mount surface type of components on pcb, can this be done or some hightech equipment is needed.
