As for the pop account, he can add that to the phone as well. When setting it up, if it is directing him to the wrong carrier, maybe it isn't really unlocked? He can try wiping the phone and re-entering the pop account.
Wiping won't do anything - especially unlock it. If he is already using it on TMO, then it is unlocked.
Does he have a BIS account set up with TMO? If so, you will need to log into the TMO BIS site, enter user name and password and set up the work account there.
