gamertag questions!!!

I currently have two gamertags TeaFace and CiD TeaFace. Currently CiD TeaFace is my main acoount since it has a 1 year xbox live memb. I was wondering if I change teaface to another gamertag will that free up the name "teaface "and allow me to change cid teaface to teaface???

I don't think so. I think once a name is used even if its deleted no one will ever be able to use that name.
