iOS Developer Bundle ID & App Name Already in Use
The answer is to create a new bundleID, update your app, and submit a new app with a slightly chanced name to Apple. No other options as far as I have seen.
I created my iOS App ID and immediately after tried to register my app, but received the error message "The Bundle ID you entered has already been used." I tried again a few hours later -- by then, Apple had logged me out so I had to log back in.
When I tried again, it worked with no errors. Not sure if it was the time delay or the log out / back in.
