Hi please ,has anyone the answer? I updated to IOS8 on my Ipad4 and it seems to freeze at different times ,mostly I have cured the prob. be rebooting. HOWEVER twice now it has frozen on the SCREENSAVER but at full zoom. Nothing seems to work. switching off,rebooting etc etc. I connected it to the iMac and tho the iMac didn't seed the iPad it cured the problem. i have had Apple since 1983 and really don't go for instability!!!!!!!!
