The iPhone 7 is hailed as one of the best smartphones of 2016. Apparently, the said device is capable of running Windows XP without having the need to jailbreak.
iPhone 7 And Older Versions Of Desktop Operating Systems
According to an article at Cult of Mac, a video was spotted demonstrating Windows XP running on the iPhone 7. Thanks to Apple's latest A10 Fusion chip featured in the iPhone 7 series, it's capable of running older versions of desktop operating systems. However, don't expect it to be something you can replace your desktop anytime soon.
To have the Windows XP or any older version of desktop operating system on the iPhone 7, you can't just simply uninstall the iOS and replace it. Instead, you will use an emulator like iBox which can be installed through Xcode without the need to jailbreak, allowing it to run Windows XP inside a virtual machine.
First downside is that getting to setup the iBox and Windows XP is a complicated process, especially if you don't know what you're doing. However, if you're familiar with side-loading apps via Xcode, then you can try it by using these files you need on GitHuB.
Second downside is that though the iPhone 7 is packed with an A10 Fusion chip and 2 GB of RAM, it offers a less than smooth experience, hence the reason as to why it won't be something you can replace with your desktop. In fact, you won't be able to do anything productive or even play Solitaire. Because it's running inside an emulator, it impacts performance significantly.
Specs And Features
The iPhone 7 features a 4.7-inch display with a screen resolution of 750 x 1334 pixels. It runs on iOS 10.0.1 out of the box and packed with an A10 Fusion chip. It has three model variations, 32/128/256 GB with 2 GB of RAM, a 12 MP rear camera, 7 MP front camera, and is powered by a 1960 mAh battery.
