Still not fixed those call failure issues on iphone 5 in Nepal....I am regretting since I have updated my i5 from 7.1.2 to 8.0....8.0.2 and still same problem in 8.1............I hate this ios...!!
For the moment i think i'll stick to 7.1.2 I'm not ready to upgrade to iOS 8 (because i consider it still has more bugs to be fixed).
Update fixes random reboot for iPad and also sound quality is improved in ios 8.1
Downloading in progress. Hoping it fixes the terrible Safari lag and the constant "a problem occurred with this webpage so it was reloaded" error messages introduced with iOS 8.0.2.
