My iMessages won't let me sign in!
Earlier today, iMessages was working on my iPhone 4 and iPad 4thGeneration.
However, suddenly it stopped working.
So i shut iMessages off and turned it back on.
It requested my apple ID. And won't sign me in... I am sure to have the right email and password as I can sign into iTunes on my Mac.
This is really frustrating. Please help me!
Thank you!
iPad (4th gen) Wi-Fi, iOS 6.0.1
