While Project Sandcastle is a huge achievement, it goes without saying that jailbreaking and rooting devices come with their own risks. The development also follows Apple's announcement last year that it will distribute special iPhones with root access that are less restrictive than their consumer counterparts for security research as part of a new iOS Security Research Device program. The result is almost equivalent to running a temporary OS on your iPhone.Ĭorrelium's Project Sandcastle comes as Apple sued the company last year for alleged copyright infringement by selling iOS and device virtualization software, including virtual versions of iOS devices running what Apple calls unauthorized copies of iOS. Thus, using the checkra1n jailbreak exploit, the Correlium team found that it's even possible to install a semi-working version of Android on an iPhone. While the jailbreak at first was only possible through macOS, it gained Linux support last month, opening up the possibility of performing a jailbreak via non-Apple devices. The only problem is that Checkra1n is just a temporary jailbreak, and will get wiped out once the phone reboots. It was initially released last November and works on the iPhone 5s to iPhone X, running iOS 12.3 and newer versions. The hack makes use of semi-tethered Checkra1n jailbreak to bypass restrictions, which is based on the checkm8 unpatchable bootrom exploit that makes it possible to gain deeper access to iOS. Android for the iPhone has many exciting practical applications, from forensics research to dual-booting ephemeral devices to combatting e-waste."įor now, only a handful of devices, the iPhone 7, the iPhone 7 Plus, and the iPod Touch, are capable of running a customized version of Android, which comes installed with OpenLauncher and the secure Signal messaging app.Įven then, there're a lot of restrictions, including no support for audio output, cellular modem, Bluetooth, and camera, to name a few, as shown in the chart below.Īll of this is only to say that Project Sandcastle is very much a work in progress. "Android for the iPhone gives you the freedom to run a different operating system on that hardware.
But when you buy an iPhone, you own the iPhone hardware." "The iPhone restricts users to operate inside a sandbox. "Where sandboxes set limits and boundaries, sandcastles provide an opportunity to create something new from the limitless bounds of your imagination," the project website says.
