Yesterday, Apple released an important update for iPhone, iPad and iPod Touch. Apple has been busy releasing earlier update in the last few weeks – just 3 weeks ago Apple released iOS 9.3.4 and this weeks iOS 9.3.5 is available for download now.

While most of Apple’s updates might not seem that important, iOS 9.3.5 is listed as an “important security update.” It fixes recent exploits which allowed jailbreaks from Pangu as well as fixes for vunrabilties in the main iOS kernel and the WebKit framework in Safari.
