I'm a huge fan of Game Centre and love everything about it, however I'm aware that you can have a personalized slogan/signature/tag
Anyway I have never had the ability to do this, the little text box that allows you to do it just doesn't ever appear and it drives me crazy. If it matters I'm using a White iPad 2 64GB Wifi only running 4.3.1 and I'm in England. It works on my iPhone 4 so I am really confused as to why it won't work on my iPad as I've seen videos of ipad users with the ability to.
Also I don't know how to send people hand-typed messages! PLEASE, PLEASE, PLEASE HELP ME! I'M GOING CRAZY!!!
