Apple iOS 10.2.1 – It’s important, you need it NOW! Read why!

After four betas and almost six weeks of public testing Apple has finally released the latest version of iOS.  The update is both essential and infuriating. So should you upgrade?  Here’s everything you need to know…

Which devices Is iOS 10.2.1 For?

iOS 10.2.1 is compatible with all devices that ran iOS 10. So this would be iPhone 5, 6 or 7, iPad 2 or later, iPad mini 2 or later, the iPad Pro range and the 6th generation iPod touch or later.

In order to download the update you should receive a prompt or notification very soon.  It should appear automatically but if that doesn’t happen or you want to speed things along you can trigger it manually by going to Settings > General > Software Update.

The actual size of the update will depend on your device – but it is looking to be about 30 to 90 mb.  It doesn’t sound like much, but this update changes  a lot.

A No For Jailbreakers

iOS 10.2.1 will not support jailbreak as Apple is really starting to crack down on iPhone and iOS hacking.  So if you’re device is jail broken, you’re going to have to sit this one out.

The 30% Battery Bug still hasn’t been fixed in this update.  Which is pretty unbelievable considering the problems it has been causing?  The story made world headlines with even the Chinese government stepping in and demanding that Apple address the issue.  A battery diagnostic tool released in December prompted users to expect a fix, but nothing has come this time around.

Apple hasn’t actually, publicly admitted that the bug exists – apart from the iPhone 6S but they should definitely get round to addressing and fixing it as soon as possible!

There have been a couple of isolated issues reported on the Apple support forums including reports of dimming displays, degraded wi-fi and Bluetooth issues.  However these reports have been minimal and could be attributed to other goings on.

What Does iOS 10.2.1 Do?

The new iOS update is a pure bug fix.  There are no features being added, just bugs being repaired and patched.  There’s not even a mention of “performance enhancements” this time around.  Something Apple usually likes to entice customers with.  It does mean however that 10.2.1 is an essential install.

The fix addresses 11 significant security vulnerabilities such as the Auto Unlock that allowed an iPhone to be unlocked when upaired from an Apple Watch, a hack that accessed the home screen via Wi-Fi even with the screen locked and the WebKit flaw that could have been exploited by marketers and ad displays.

But the biggest fix comes in the form of a serious security flaw where a hacker could take control of your entire iPhone.  Not one, but two!  Luckily, this has been fixed.

“[Hackers] can add files, delete files, or execute any actions,” explained JP Taggart, senior security researcher at Malwarebytes. “Want to record conversations and forward them to someone else? It can do that. Want to install additional malicious software? It can do that. Want to uninstall programs on the affected phone? It can do that. Want to hide these actions, programs and files from the user? It can do that too.”

Those serious security issues were never made public or leaked – so luckily no hackers ever got hold of them and a serious threat never developed from the issue.  Had the information been leaked, things could have been much worse.  However, they are now in the public eye – so you MUST update your device immediately.
