The Nikon D70, Canon Powershot G5, Olympus C5000US, and many many others use one type of USB Cable while the Coolpix 3200 and smaller cameras use a slightly smaller plug.

I want to get a replacement USB cable for my D70. Do I want the Mini-B cable or just the Mini?

I do not have the USB cable with me in the UK as I usually transfer photos using a card reader (much faster) but after looking at my D70 I think it is the Mini B like the one you can see here (http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=245207&CatId=447)
I am not sure at all though! Better to ask at depreview :)
The cable name is UC-E4 USB if you get it from Nikon.
