Cell phones: I need help finding a replacement part for my phone

I need help finding a replacement part for my phone

I currently own a Sony Ericsson P800. It was my uncle's until he got a new phone. When I got it the keypad wasn't working because one of the "teeth" was broken. I easily found a replacement part. But the 2 parts that I have a REALLY hard time finding is the Camera and more importantly the Jog Dial. The camera is a messed up because it looks like one of those heat sensors and the jog dial just doesn't work except when you press it in. I really just have to find the jog dial as that's the most important part for me. I've looked on ebay and various cellphone shops online but I still can't find the parts. Does anyone know of where to get them?
Any help would be greatly appreciated.
