I can swap one gt for another right?
For example lets say gt "A" is the gt I want on my main account which we will call gt "B". If I change gt: "A" first to some random tag then change gt: "B" the gt: "A" will it be available to use correct?
Xbox LIVE Costumer Support told me that after you change your Gamertag, it won't be available for others for 14 days. This means that your old gamertag will be reserved for you for 14 days in case you want to change it back (This would still cost you 800MSP).
