I bought this after searching on here for "USB cable Nokia 6300", it's very cheap and it came quite quickley. However, after several attempts and internet searches for advice, I still couldn't get it to work. Finally, I did what I should have done on the first place and checked the Nokia site for compatibility. The correct cable for the 6300 is a DKE-2 DATA CABLE, so I bought one of those and it worked straight away.
