i upgraded IOS 10 on my 6S. Once this done the device is frozen
i upgraded IOS 10 on my 6S. Once this done the device is frozen whenever I am trying to send a sms, mail, what's app... or even put the pin code. Never happened with previous versions of IOS and Iphone devices.Apple is telling me there is a conflict between IOS 10 and my Exchange mail account, plus between the same IOS 10 and my icloud account. They say I have to change for an IMAP account and create a new icloud account. we tried resets, restore back up, change device two times, but still it is not working, and everything is lost. Thanks for your help.
