Hi there, my USB port also broke of. I managed to solder a replacement port on the PCB. Now I have some problems, that the N900 will not always recognise when I plug the wall charger in. In that case, it will not charge. What is even more strange: IF it is charging, it will not recognize when plug the wall charger OFF - it keeps thinking to be charging. Rebooting helps then, so I can live with that. But still, very strange.. Any idea, whats going on there?
