As we all know that recently Apple has released its latest iteration of iPhone, the iPhone 5. The new iPhone came with the all new iOS 6 operating system that brought so many new features and improvements over the previous version. Now, just like the old times, whenever a new iPhone model and iOS versions are released, all the developer teams and individual iOS enthusiasts start to work very hard in finding new loopholes and gaps left by the security team at Apple. Well, these loopholes and gaps can be used as threats for the users but the main reason why they put all this effort into finding them is for jailbreaking and unblocking of that particular version of iOS.

Difference between Unlocking & Jailbreaking

Well, you have to keep in mind that both jailbreaking and unlocking of iPhone are not same, they are completely two different things. They might have some similarities in terms of the job they have to do but their difference is very significant as well. Basically, when we jailbreak a device, it only allows users to alter or modify the internal settings of the device and also install third party apps that are not allowed at official App store. On the other hand, an unlock for iPhone is used to allow users to use any network carrier’s SIM card in their device.

Mostly people buy their iPhones from carriers because there they get special discounts and slashed prices and that is why most of the iPhone owners end up with the carrier version of the device. So, if you have an iPhone 4 unit that is from some specific carrier, you will not be able to use any SIM card from any other network. In case you have to travel to other countries or for some other reasons you want to change your carrier, you won’t be able to do so because of the carrier lock on your iPhone 4.

So, that is the main reason why an unlock solution for iPhone 4 is necessary and developers are working very hard to find the exploits in the new iOS 6. So, if you want to unlock your iPhone 4 with iOS 6, first of all you will have to get your device jailbroken. After that, all you need to do is just get a utility named Ultrasn0w Fixer for iOS 6 at the iparelhos repo of cydia. This utility will be able to unlock your iPhone 4 while running on iOS 6.
