They said that iOS6 has security issues, and so I had not much choice but update to ios7.
I did not upgrade to ios7 because it’s new UI effect is nauseating.
And, thank God, I’m not alone because when I googled for for help on how to remove this “flying-everywhere” effect on iOS7, others are also complaining about it. So I was not really being OA about it. It truly was annoying.
