Don't get iOS 7 yet..

link :

Given all these bugs and issues, combined with some genuine major advances, it’s hard not to interpret this as a beta release that was rushed into production for the release of the iPhone 5S. In a way, it reminds us of the Android 3 release — which was rushed into production for the Motorola Xoom tablet — with severe bugs and performance deficiencies. We’re eagerly awaiting the release of the first update for iOS 7 when we hope Apple delivers on its usual commitment to quality.

I have experienced alot of my applications not working. For example, GMail keeps crashing on iPad and MyFitnessPal on iPhone also crashes when attempting to enter text.
