Allright guys, this will be my last update to this thread. The how-to will stay up indefinitely (until Google decides I've taken too much bandwidth). I did my absolute best to come up with a method that will improve the USB port strength without endangering the N900 internals.

I even verified that the Epoxy I used is safe for electronics, that it doesn't shrink (I even called Permatex and they confirmed it) and that, while far from perfect, it does stick to PCBs. Now only time will tell. But I will say that I've used Epoxy in a variety of circumstances, and it held up far, far better than any other adhesive I've ever used.

Good luck with any of the fixes you chose to implement.
