If you've not yet switched over to one of the newer iPhone models you definitely need to head to your settings and download the very latest update from Apple. The US technology firm has just released an urgent iOS upgrade and it's vital that it's installed as soon as possible.
This important patch, which is being pushed out to models including the iPhone 7, iPhone 6 and iPhone SE, fixes a number of flaws including one that's been given a so-called zero-day rating.
For those not clued up on this terminology, that zero-day stamp means hackers are aware of the flaw and are actively exploiting it. That's why there's an urgency to update devices as soon as possible.
