It is not a secret that there are a lot of various methods on how to unlock iPhone. Users can get third-party programs that change their smartphone’s code or use factory unlock. Some tools are free to get, but other services are paid for. Right now I want to tell you about an unconfirmed exploit to factory unlock any iPhone 4 / 4S runnig any firmware like iOS 6.14 / iOS 6.1.3, 6.1.2 or even 5.1.1 with the GSX help. Keep in mind that this method might work for you only if you don’t live in the U.S. because it it still illegal to perform iPhone unlock in the United States.

GSX Exploit to Factory Unlock any iPhone 4 / 4S [Unconfirmed]

First, I’ll explain what Apple’s GSX tool is. You can find it on the official site of the Cupertino-based tech giant at gsx.apple.com. This system is available to particular groups of users. For example, you can use it if you are a service provider and need to order device’s parts or process repairs. But you cannot access it if you are an ordinary user. Secondly, there is no way for you to unlock iPhone with GSX if you are not one of authorized service providers working in partnership with Apple. In other words, if you don’t have a GSX account you are not eligible to get unlock for your iPhone. Surely, there is a way to get such account if you become friends with iPhone carriers or repair shops that already have one. But this task is too difficult to achieve. If you are lucky to get important contacts at a repair shop or at the mobile operators, you should get a list of IMEI numbers on activation policy that unlocks gadgets’ status. The best is to find somebody from some Chinese repair shops or those who have serial numbers of iPhones from China Unicom, China Service and other. To start with you need to have a GSX account or somebody who has it. Step 1. Think about a reason [a fake one] why you need to repair an iPhone. Step 2. Visit GSX Apple site and create a new “carry-in repair” tool. Mention the reason you have thought of in Step 1 and wait till your repair case is approved. Step 3. You will be able to put the “New Serial Number” for the handset you wish to unlock. Actually, this area is designed for a replacement iPhone you need to transfer Apple’s warranty over to. It also transfers the activation policy with the unlocked status over to the iPhone. Simply enter the serial number of the handset and it will become unlocked.
