    He is obviously on 1.59 baseband if he has an iphone 4 which is unlocked.

    You have two options you can upgrade to 4.1 using Tiny umbrella google for instructions and do not ignore the readme. Alternatively you can wait for Dev team to release a new version of Pwnage tool which will give you the ability to upgrade to a custom ipsw and retain baseband.
