How to I transfer music recorded by iPhone 4 to my computer (apple) ?

[iMore Question]

I have a new iphone 4 and I've recorded some live music onto it. How do I transfer it to my mac computer so that I can hear it?

What does "this accessory may not be supported." mean?

It's means the cord you're using is not an Apple approved accessory so the computer doesn't recognize it.
