I got it working I think. I'm waiting for my brother to wake up to test but this is how I did it.
go to the 3G unrestrictor app>edit>+>add phone from the list. hit done. then hit the arrow on phone on the list and turn on "enable isdirect flag". now you can at least make a FaceTime call, but like I said no one is awake I can test if the call actually goes through. someone test it and tell me if it works plox.
