well .. mine broke recently aswell. I managed to get a new port soldered onto it (took me 6 hours). It worked !!, i then decided that my solder work was a little to shabby and that there was not enough solder on the supporting structure that is soldered onto the pcb and proceeded to try and get more solder under the body of the connector. It turned out to be a BIG fail!. The port broke of from the pcb taking all copper islands with it.

I have now proceeded with another solution. I have used a prototype pcb and soldered pins onto it which touch the test islands for the usb port on the n900. It all works well, however i can can obviously no longer put the original casing around it. Iḿ looking for a solution for this too. anybody got any ideas.

Iĺl post some photos if anyone wants.
