If you want to make your own iPod/iPhone hardware, apply at http://developer.apple.com/ipod/ http://developer.apple.com/ipod/ Last I check it requires multiple in-company points of contact and legal contacts before you start. You are charged a licensing fee for each unit sold and they revoke your access if you don't renew your contract with them. There are some iPhone in-car systems that stopped working because the manufacturer didn't continue paying Apple the appropriate licensing fees (so in the next software update, Apple disallowed that device from talking to the phone).
