Ok, saving my life is probably an exageration. But I just ordered these three cables from Amazon and I LOVE THEM!
This first one is a 6 ft Dock Extender Cable for iPod/iPhone (they have both black or white cables and 6′ or 2′.) If your iPod has a case and you have a speaker system, then you know how it sucksass to have to pull your iPod out of the case to stick it into the speaker system.
Cool, eh? The next two are for standard audio systems, but if you have a case, you’ll want at least one of these. They both connect to the dock connector instead of the headphone jack… so the audio feed is a much a higher quality. I picked up both of them because I like the flexibility of being able to go to RCA or 1/8″ plug.

Let me know if you have any questions about these, or if you pick one up too!
