Basically, my iPhone 5c automatically restarted itself one day. Since then, I have been asked to "activate my iPhone", however, I am not able to connect to wi-fi. When I use cellular date and sign in, I get a "activation servers are temporarily unavailable" notification. When i plug into my laptop and sign in, I get a "Activation information is invalid" type notification. My phone has been with me and it's original provider since being bought brand new (so never jailbroken). Is it repairable?
