Where form meets function

Two days ago, Apple released its iOS 11.2.2 software update for the iPhone, iPad and iPod touch.

Current reports suggest the new security update doesn’t affect or change apps and features. Instead, the upgrade is a security response to patch Safari’s vulnerability to the recent Meltdown and Spectre cyber attacks. While Apple recommends the update for all users, here are a few things to note before you take the plunge.

Spectre and Meltdown

In a statement released by Apple last week, the company warned that all hardware operating on iOS could be affected by the recent Spectre and Meltdown attacks. As there is no hardware fix for Spectre, the attack could potentially allow hackers to gain access to sensitive information. In response, Apple implemented initial safety measures, but now recommends the new update – available for iPhone 5s and later, iPad Air and later, and the Pod touch 6th generation — to increase device security.

Security improvements to Safari

Apple says the update includes security improvements to Safari and WebKit which mitigate the effects of Spectre. Notably, Apple warned that the update may slow Safari down slightly, but that’s a small price when taking the overall picture into account.

Additional information

If reports are to be believed, the security update has little bearing on battery life, nor does it affect Wi-Fi or Bluetooth. Apple has an iOS 11.2.5 update, said to bring about wider changes including a Siri upgrade, currently in BETA testing, but it remains to be seen whether 11.2.3 and 11.2.4 updates will precede its release.

Make sure to stay posted for any further information regarding iOS 11.2.2. If you’re worried about performance levels on your iPhone, Apple is currently offering battery replacements for its devices.
