I have been using ios since 3gs and i have changed various iphones already without problems to my account.
So recently i changed my 5s to a 6+ and i find that my game center account is different but im still using the same
apple id i created many years ago.
First, my nickname is different and when i try to change it back it says "This nickname is already in use by another account",
my score is different also the games too and my friends list is gone.
Can anyone help me with this please.
P.S. The first image is my original account and the next one is my current account.
