iphone 4S displays Activation Required every reboot/every couple of days
Since the IOS8.02 upgrade my phone constantly drops to "Activation Required" lock and won't activate over cellular connection (Vodafone UK). This means I'm stuffed until I can connect to WiFi, when I enter the ID details and all is OK. Very annoying if I'm away from home!
I've done a Recovery Mode restore through itunes but it's still the same. The phone has never had any developer betas installed and, until the past couple of weeks, has operated all OK with earlier IOS versions. When activated all is fine with 8.02 too, until the next time it locks itself :-(
