Recently my friend bought a new Apple iPhone. As he use different sim cards, he wished to unlock the same. So, he approached me for help. I have already dealt about different iPhone unlocking solutions and just had a look about the same, but they all seemed not to work fine due to the reason that the new iPhone is of firmware version 2.2.1. Finally I found a solution to Unlock iPhone 3G 2.2.1. Here goes the details about this.

If you want to know how this is different from others is that many other solutions do not work on the latest Apple iPhone 3G 2.2.1, but this one does very fine. Few of the iPhone unlocked with software solutions got locked after getting updated to the latest firmware. But this one is not such case and the company claims that this will work fine for any update.

If you are interested to know how it works – it is a "piggy back sim" which is a very thin sim card which you need to place it over the sim card which you use – provided by your mobile carrier. This special sim card addon will simply make the iPhone to believe that it is the original one. And thus this unlock iPhone 3G procedure is safe and does not affect any of your hardware, software or firmware.

The main drawback with software solutions is that the iPhones get locked after each update and it may also void the warranty. If you want to know more details about this safe and secure way which works all over the world with any network with no hassles and no technical knowledge requirement, please go through the details at iPhone 3G Unlock page.
