This hacking tool can unlock an iPhone 16. Here’s how it works

Apple does not assist third parties in unlocking iPhones, which has led many law enforcement agencies to rely on the Graykey forensics tool. A recent report from 404 Media indicates that this controversial product can now access the newest iPhone 16 models.

Should this be a concern for you? Almost certainly not, but it’s still good to stay informed about how these things work. Here’s a quick overview.

A new report states that Graykey can access “partial” information from iPhones running iOS 18 or iOS 18.0.1, including the iPhone 16 lineup. What “partial” information means is unknown. Leaked documents also suggest that iPhones with the iOS 18.1 beta are inaccessible to Graykey. The same restriction is believed to apply to the official release of iOS 18.1, which became available to the public in late October.

Graykey, like another law enforcement-used unlocking product, Cellebrite, is very secretive about how its products help unlock iPhones. What we do know, however, is that these companies look for new iPhone vulnerabilities to do their job. As Apple patches security flaws, companies have to find new ways to access data, and so on.

Since at least iOS 12 in 2018, Apple has continually identified vulnerabilities that make iPhones susceptible to unlocking and subsequently released software patches that address the issue. Eventually, third parties find new vulnerabilities, and so on.

As 404 Media indicates, Magnet Forensics, which owns Graykey, could eventually find ways to unlock iOS 18, iOS 18.1, and subsequent versions. Apple developers are currently testing iOS 18.2, which should be released to everyone before the end of the year. The leaked documents don’t mention this version.

It’s important to note that products like Graykey and Cellebrite need physical access to a device to function — if they can at all. This isn’t something you’ll run into in the wild and cannot be done remotely.

User privacy has always been one of Apple’s core principles. As a result, its products, such as the iPhone and iPad, are protected by strong encryption. The company has consistently resisted government requests to create a “backdoor” for data access.

For individuals concerned about unauthorized access to their phones, ensuring they have installed the latest software updates is the best course of action. For iPhones, this means updating to iOS 18.1.1; for iPads, the update is iPadOS 18.1.1.

This one iPadOS 26 feature has me excited for the iPhone Fold
Semi-open state of a foldable iPhone concept

Samsung is set to launch the seventh generation of its Galaxy Z Fold book-style folding phone this Summer, but its biggest rival is yet to show its folding phone hand. Apple has long been expected to unveil an iPhone Fold, and the latest rumors suggest that it will launch next year.

I’ve used almost every folding phone released globally, with some exceptions for extremely obscure ones. While I've always been curious what an iPhone Fold would look like, I was fairly certain that Apple shouldn't build it, as I wasn’t sure they could deliver on one necessary feature.

These three iOS 26 beta features are my favorite so far
The Liquid Design lock screen on the iOS 26 developer beta 1 running on the iPhone 16 Pro

For fans of the Apple ecosystem, it’s been an incredible week. Apple’s annual WWDC 2025 keynote revealed a whole new Liquid Glass design that’s unified across all its platforms. Also unified across all platforms is the numbering scheme, with iOS 26 designed to represent the year of release… plus one. 

The new platform doesn’t deliver one of the key things I asked for — multitasking, which is available on iPadOS 26 — but it does bring several new features that make the iPhone far more usable.

iOS 26 features on a series of iPhone screens

Apple announced iOS 26 at WWDC 2025, and the new iPhone update comes with a fresh new 'Liquid Glass' look and plenty of features - and there are loads of iOS 26 supported devices, which is great news.

And no, you haven't missed a volley of updates since iOS 18 in 2024. Apple has skipped a bunch of numbers, so instead of giving us iOS 19 in 2025, we got iOS 26 alongside iPadOS 26, macOS 26, watchOS 26 and tvOS 26. In short, Apple's brought its operating system numbering into line. Nice.
