Apple has released iOS 8, the latest version of its mobile operating system, for iPhone, iPad, and iPod touch. Users can download the new software by navigating to the “general” tab in their device’s settings menu and selecting “software update.” If you don’t want to download the update wirelessly – perhaps you’re on a restrictive data plan and have limited Wi-Fi access – you can also connect your phone to the latest version of iTunes to download the update. The iOS 8 update pack weighs in at 1.4GB and requires a staggering 5.7GB of free space to install on an iPhone (6.9GB on an iPad), so you may need to delete something like half a dozen games to free up some room before you get started.
Lots of improvements over iOS 7, so definitely worth it. Do pay mind to the hefty space requirements, though.
