Iphone 6s dead and I do not remember icloud email
a while back my old iphone 6s soaked in water and i do not remember my Icloud email( i remember my icloud password) and it does not turn on at all. Is it posible for me to take it to an apple center to see if they are able to retrieve my info or at least my icloud email because that is basically all i need so i can login in my mac?
