How to iPhone unlock using Jailbreak
When compared to jailbreaking, unlocking an iPhone is a different process. iPhone unlocking is the process of removing the carrier’s network restrictions.
What Is the Function of an iPhone Carrier Lock?
Carrier locks, unlike other types of iPhone locks, do not alter the device’s hardware or software. Every iPhone has a unique IMEI, and to add a carrier lock, your carrier simply changes the database entry for your iPhone’s IMEI to “locked” and specifies the carrier to which it is locked.
When your device detects a new SIM card, it also detects the carrier and checks the IMEI database.
For example, if you buy an iPhone from AT&T, it is locked to that carrier. This means you are not permitted to use any SIM card other than an AT&T SIM card. Once you’ve unlocked your iPhone, you can use it with any carrier, anywhere in the world.
However, iPhone Jailbreak is required for unlocking. There were popular unlock jailbreak tools such as UltraSn0w and BlackSn0w in the early days. Unfortunately these tools are not supported with the latest iOS versions or device models. If you need jailbreak / unlocking solutions for latest versions please refer to the following pages.
