iCloud Activation
I restored my iPhone 4 running iOS 7.1.1 because it was running really slow and now that i restarted it, i cannot activate it because it says that the acccount linked to this iPhone is (k*****@icloud.com) which is not because I'm 100% sure that this is not what I used to set up my iphone. This is not stolen or second hand, I just dont know what to do,Please help!
iPhone 4, iOS 7.1.1
