If you're looking to unlock your iPhone, you've come to the right place. iUnlock is a free application for Windows users that lets you use any cell carrier you want. This software works by allowing you to use any Sim card. This will make your iPhone more versatile, and you'll be able to switch carriers with ease. You can download it for free from HaRRo Inc.'s Web site.
It's available on the web for free, and there are several methods for unlocking your phone. There's a manual method, and you can also try iUnlock on your own device. It's easy to use, but it's not a user-friendly solution. Before you can use the tool, you need to jailbreak your iPhone and access a Unix command line. You may also need to use SFTP or SSH. You can even use a GUI tool, but you'll need a computer with some basic skills.
While there are many free solutions for unlocking your iPhone, they're not the best option. If you want to use unapproved programs, you'll need to jailbreak your device first. This method will also allow you to tweak and customize your user interface. However, you won't be guaranteed against future updates by Apple. Moreover, you'll have to pay for the software again if you want to use it. Then, you can use the tools on your phone to make it compatible with the latest versions of iOS.
