Anyone with an iPhone in their pocket should check that it's updated and running the very latest version of Apple's iOS operating system. It's an important piece of advice with those who haven't - or simply can't upgrade their phones - set to lose some key functionality next month.
According to one top tech tipster, Apple is planning to block some older devices, running ageing iOS software, from using services such as the App Store, Siri, and Maps.
"As of early May, access to Apple services, with the exception of iCloud, will stop working on devices running iOS 11-11.2.6," the @StellaFudge Twitter account revealed.
Although this has yet to be confirmed by Apple, the US technology giant has recently posted an update on its support pages which could back up these claims.
"Some older software versions will no longer support Apple Services like the App Store, Siri, and Maps. Update your software to the latest available version to continue using these services," the company said.
Luckily, even if the reports are correct it shouldn't affect too many users with only devices that were launched before the iPhone 5s losing access.
Those with an iPhone 5s and all of its successors such as the iPhone 6, iPhone 7 and iPhone 8 should find they can switch to a newer OS such as iOS 12.
Here's how to check your iPhone for updates.
• Back up your device using iCloud or your computer.
• Plug your device into a power source and connect to the internet with Wi-Fi.
• Go to Settings > General, then tap Software Update.
• If you see more than one software update option available, choose the one you want to install.
This latest iOS news comes as Apple is about to reveal more news about its future software releases. The company recently confirmed that it will hold its annual WWDC Developers Conference on June 5 and there are sure to be plenty of big announcements including the first look at iOS 17.
The global event almost always throws up a few surprises with Apple using last year's WWDC to reveal its stunning new MacBook Air.
However, 2023 could be even bigger with rumours rife that a new VR headset will be shown to the crowd that gathers at the Apple Park HQ.
These gadget googles could mix virtual and physical worlds together allowing users to overlay data and graphics on top of what they are viewing in real life.
“WWDC is one of our favourite times of the year at Apple because it’s an opportunity to connect both online and in person with the talented developers from around the globe who make this community so extraordinary,” said Susan Prescott, Apple’s vice president of Worldwide Developer Relations. “WWDC23 is going to be our biggest and most exciting yet, and we can’t wait to see many of you online and in person at this very special event!”
