This started yesterday where my iphone would prompt me to sign into icloud several times. I tried to sign out of my icloud but I also have find my iphone off. When attempt to turn it off it says "there was a problem deregistering this iphone with icloud. Try turning find my iphone off again." I'm jailbroken and would like to keep that if possible. I resetted my setting, tried the wifi trick not sure what else to try and suggestions?
