iPhone won't transfer Music from new Macbook Pro

[FuNyuN]

I just bought a new Macbook Pro and now it's as if my iPhone doesn't trust it. I can't do anything I could do with my old MBP. The only thing I can do is charge it. Is there a file or something I need to transfer from my old MBP to get it working properly?

Edit: My iPhone is jailbroken, so if there's no normal way to do this. A jailbroke method would suffice.

Any ideas?

have you authorized the iTunes on your new MBP?
I don't know anything about jailbreak or not but every device needs to be authorized in iTunes.
