Today iOS 7 has been released and therefore every media is focused on it, especially social media. And as this update to iOS brings singificant changes, most notably in the GUI and UX (I dont't want to point them out here, there are enough other sites doing it already), there is a controversial discussion. A lot of people (like me) dislike the gaudy colors, and for me that's the moment to point once again to the Jony Ive Redesigns Things collection.

But what isn't mentioned…

… is the fact that iOS 7 not only a update to the user interface, but also fixes a lot of security issues and bugs like most updates do.

This is a list of all issues fixed according to the official Apple Product Security mailing list which everybody can subscribe:
