HHi Emma, trouble is that link is only for back to iOS8, which in my case is worse than iOS8.02 but that is worse than iOS7.12, which there is no going back to 😟
I ve another problem, im on an iPad4 retina display, wi fi only, often nothing happens when I try to log onto pages, sometimes enlarging the picture on the screen then going back to normal can stop its 'freeze' but not always. The Google search will scroll up and down ok but won't log into anything. It doesn't even try, its as if it's frozen. Does anyone know why, or is it likely just another glitch with the iOS8.02. I never had this happen before the iOS 8 update btw.
