App name already taken....

So my app name is already taken. Actually all app names are taken no matter what I pick even though there are NO games on the app store with said app names and no trade marks have been filled. I still don't understand what is going on in this regard.

My question is this can I register the app with a place holder name such as "Booger Gobblers 666 ***" then later delete this app and re register it with the actual trade marked name? Or is this not allowed? Of course I will only do this for test purposes and will not publish on the app store with this name (It would probably be rejected anyways based on the name).

I need to do this in order to continue developing the app by connecting it to Game Center and using the GameKit API.

Thank you in advance for any help!
