Q: How do I unlink my iPhone from my iTunes?

Hi Fellow Tuners,

I used to link my iPhone with my MBP, but I bought a Mini to use as a server and have moved all my content there, including my iTunes library.  I've successfully linked my phone to the iTunes on my Mini server, but every time I turn on my MBP iTunes opens and thinks that it is still linked to my phone.  I've deleted my entire iTunes folder (on the laptop) but it doesn't help; I'm sure there's a library file floating around that is giving it old information.

Anybody know which files I need to delete to permanently break the connection?
