if you are like me , you must have already update your iOS device to iOS 9 beta.

As much as I like the upgrade , the sudden application crashes make it a bit difficult to live with it such as my Mail application is very temperamental , it opens when it feels like , this is to be expected when you have a beta.

iOS 9.0 Beta 2 Senseapplied

However the update today seems to solve the problems ,for me it the download as quick , it installed even though I had only 40% battery left and took around 5 min of phone downtime to install.

So if you are getting the notification , go for it
