I had to do a reset on mine and I had the same issue trying to sign into my gmail account via the main settings. It would work in other email apps but not let me add the account at the system level at all. Seems to be ok today. I wonder if it was due to the Google Plus breach.
I think so. Google was on semi lock down yesterday. The weirdest part was that I was receiving log in notification emails from google even though the account wasn’t on the iPhone.
