[iMore Question]

my iphone 4 keeps popping up sign in to Icloud every 3 seconds,

I share a plan w/ mom, step dad & son, Ive inherited my steps dads phone so he had programmed all kinds of things on it earlier when he had it. Now it is popping up message 'sign in go Icloud' every 3 seconds, it just started doing this today.

Have you tried signing in (having your stepdad sign in)?

Or removing your stepdad's Apple ID and signing in with your own Apple ID?
