One night I decided to get a whole lot more apps and installed about 20 or so of them onto my n900.

I then plugged my charger in and the phone won't charge, it also won't detect a computer via USB.

I went through and uninstalled every program possible on my phone but the USB port still doesn't work, I also tried restore to factory defaults in settings.

Although this could be a coincidence (usb happened to break at that exact point in time) I think the solution would be to reflash my phone to confirm but I'm not sure if you can do that without a USB port.

I have an external battery charger and I can use my phone with that now but it is a pain in the *** as I have to take my phone apart every night.

Before I write my phone off as having a broken USB port can anybody think of anything else I could try?
