When it comes to unlocking your iPhone, the most preferred way is to do it using software, even though you can do it by modifying its hardware. It is essential to check whether you can unlock your iPhone before you proceed as unlocking an iPhone hasn’t always been possible for all firmware versions.

In order to unlock your iPhone, you need to jailbreak it first. Jailbreaking an iPhone has become pretty simple and straightforward. All you need to do is download jailbreaking software specific to your operating system, plug your iOS device to your computer, and run the software. You can easily find enough jailbreaking tools for Mac and Windows.

Here are few steps you need to check before you try to unlock your iPhone:

1. Make sure that the carrier you wish to go for uses GSM, as iPhone uses GSM for its communication. If you try to use CDMA carriers then you may not be able to unlock it.

2. You need to know your iPhone’s firmware version and baseband version. Depending on your iPhone’s baseband version, you can search the latest unlock tool on net. If you don’t get the right software for the right firmware, then unlocking can turn out to be a tetchy experience.

3. Whether you are planning to unlock or jailbreak your iPhone, it is better to stay away from updating your iTunes, as a new update could prevent your iPhone from unlocking.

4. Before you download an unlock tool, you need to verify its compatibility with your iPhone model. This is usually given in the description section of the unlock tool’s download.
