In this post I am going to tell you about the various methods for unlocking your iPhone 4/4S available these days. But before I start I would like to tell you what unlocking is all about?
What is Unlocking?
As you might know, that iPhone comes of two types one is factory unlocked, in which all SIM throughout the world are supported. The cost of factory unlocked iPhone is much higher as compared to that of a Factory locked or a carrier locked iPhone. You might buy an iPhone with At&T and might want to use it with some other carrier which is cheaper and has got better reception in your area, or you may not want to go for an iPhone for a higher price when you can get it much cheaper.
Especially in country like India where you get the iPhone 4S 16 GB for around Rs. 45,000, buying an iPhone 4S from U.S or Canada in Factory locked or even unlocked version might be a cheaper option.
So by unlocking you can relieve yourself from the bond of your iPhone with the network it is locked to and enjoy any network in any country.
Difference between Unlocking and Jailbreaking?
Jailbreaking is a software modification in your iPhone’s software that allows you to run unsigned codes that allow access to files that normally Apple does not allow. Jailbreaking adds Cydia to your iPhone which is the app store for such codes and third party applications which are not available officially.
Jailbreaking is legal now, though it voids your warranty. Jailbreaking is very useful and some of the features that it adds are:
- Changing the looks and graphics of the iPhone UI and it allows you have much more personalization options.
- Free tethering.
- Access to cracked app store apps for free.
- Installing third party applications rejected by apple.
- Ability to Unlock iPhone.
- Enhancing capabilities of iPhone such as Bluetooth, camera, recording and much more.
Unlocking is removing SIM restrictions from the modem and allowing the use of iPhone on any carrier throughout the world.
There are two main types of unlock:
- Hardware unlock- in which certain hardware changes are made, for which opening of iPhone is required.
- Software unlock- iPhone is usually unlocked via softwares.

Gevey SIM

It fits into the iPhone SIM card tray. It is a microprocessor that sits between the SIM card and the baseband hardware.
You need to buy gevey sim. It may or may not require a jailbreak, depending whether you have activated it using the original carrier SIM or not. After you buy and jailbreak your iPhone you need to use gevey sim along the SIM you want to use. It also supports Unlock for iPhone 4S unlike Ultrasn0w.
