I should add to this thread - that 5 pins is apparently not enough to buy the right mini usb. I bought two more, that unfortunately don't work for me! Fortunately, they only cost me $2.50.

I compared them to the one I have that DOES work for syncing - and as someone else pointed out, that one from Insten, has 3 wires. The non working ones all have 2.

Unfortunately, in listings I only see vendors distinguish between 5 and 4 pin. Not about number of wires. So you've got to go with brands and types that people have reported to work.
