I bought my D70 about half year ago and I always download my pictures by usb connection using the supplied usb cable. But recently I´ve noticed some contact problems and it seems to be the camera since I tried another brand new usb cable, it looks like the mini usb inside the camera has its days counted already. What should I do? If its a common problem it wouldnt help much servicing it. Should I buy a CF card reader? But removing and putting card back to the camera many times woulndn´t cause it to spend the cf connection like the usb one?
