How do I take apart an Apple iPod Connector? The cable, not the part on the actual iPod.
Joke: it's easy to take it apart. Do you need it to be usable afterwards?

Thomas' suggestion is a good bet, but the pliers will likely damage the connector (the gray plastic). 

But if you only care about the connector and not the housing (the white plastic), then you could cut the housing open without touching the connector itself. 

It depends on what you want to do after you've taken it apart, but you don't mention that.
