Software and Hardware Unlocks for iOS 8.3 version

You can skip this part if you are interested only in unlocking your iOS 8.3 updated iPhone, but it is always good to know your options, and why some method are not working anymore.

Software Method:

How to Unlock iOS 8.3 version

You must Jailbreak your iPhone first, and then through Cydia, you need to install Ultrasn0w, which is the unlocking tool. This method is exploiting bugs that are found in the iOS versions, but Apple is trying to eliminate them. For the jailbreaking part, the PanGu tool supports the latest iOS versions, and even if it wasn’t, the Jailbreaking community always find a way to achieve it. The unlocking part (which is the one that matters most), is a different story. The team that is responsible for the Ultrasn0w tool, has been idle for many years, and it is useless for the iOS 7 and above versions. So, if someone offers you a software unlock for money, it is 100% sure that they are trying to scam you! The Software Method cannot unlock iOS 8.3 version!

Hardware Method:

This method does not require a jailbroken iPhone, and it is not using a tool for the unlock. The hardware method uses a specially designed SIM-Card, which must be squeezed with your original SIM-Card. Many companies are popping up, that are selling these cards, so you must be very careful. This method does not have very good feedback, and it cannot always unlock an iPhone, especially if it has the latest iOS versions. Many people reported low voice quality, drop of phone calls and failure of unlocking an iPhone. We highly recommend to stay away from that method, because not only it costs, but because it is a high risk solution. The Hardware Method cannot unlock iOS 8.3 version!
