Used iPhone 13 Pro with iOS 15.0.1
This iOS version supports jailbreak. It has been very popular to jailbreak your iPhone to avoid Apple's restrictions. However, Apple has made it much more difficult to jailbreak newer iPhones in recent years. iPhone 13 Pro and iOS 15 are one of the latest "jailbreakable" versions. iPhones on this iOS version are hard to find as most update their iPhones automatically.

The iPhone works perfectly, even in Jailbreak mode. Jailbreak can be voluntarily and easily installed on the mobile, and you can switch between jailbreak mode by simply turning the mobile off and on. The system is stable and popular online banking apps also work as usual. I've been using the Dopamine jailbreak on it myself for over a year, with no problems.

Jailbreak lets you "tweak" your system and install apps outside of the Apple App Store. Then you can e.g. install game emulators, modify apps to remove ads, add cool effects to iOS, customize the interface, access tweaks and features not normally allowed by Apple, and improve performance or battery life with certain tweaks. I would say that it is relatively user-friendly to tweak your iOS, but it is definitely a better experience if you already have an interest in software and technology, or have tried it before.

The iPhone is from October 2021, used for just over 2 years. There are a few small scratches on the screen that you cannot see when the phone is in use. There is also a slightly more obvious scratch on the edge of the phone. The battery's health is at 83%.

One original Apple Silicone cover is included, as well as one screen protector from Spigen. Original packaging and receipt are also included.

I myself have upgraded to an iPhone 14 Pro, and am therefore selling this iPhone :)
