So I woke up this morning and the phone completely locked up. A hard reset was required (resulting in a currupted pixilated looking screen) to which all my passwords had been reset. I was also prompted with the deactivation screen and briefly the Hola/Hello... message as if it was a new install. All apps were still present but I had to re-enter all passwords for mail and calendars etc. I'm on beta 8 (latest). 6S. Has anyone else experienced this?
