Some face delays activating new iPhone 4S
Found an old iPhone 4s of mine a couple days ago, any idea on how to activate it? : r/iphone
Can't activate iPhone 4s. I just factory reset it through the settings app and it won't activate now. It's running iOS 8.4.1 and I DON'T want to update it to iOS 9.3.6.
