I am a die hard iPhone fan and since three years I am using iPhone. First i had iPhone 3G, then I got an iPhone 4S, now I have bought a new iPhone 6. I can't even think of moving to other devices. iOS 8 is simply superb.
The iMessage in my iPhone 6 was working fine, now I am facing this problem. I think I have been logged-out from my Apple ID account automatically, but why I have been logged out of my Apple ID automatically ?
