Cannot activate iphone 4s on iOS7
I have an old iphone 4s and I installed iOS7 on it. Whenever I try to activate it with my own AppleID account, I just get a failed error saying it couldnt activate my iPhone. no matter how many times I do it i get the same error. My Apple ID is fine, i know because i even used it to log into my icloud.com/find and i was able to successfully locate my ipad, mac, iphone5 and iphone4s.
So I dont know what the issue is.
MacBook Air, OS X Mavericks (10.9), Late 2012
