Jailbreaking is basically modifying the iPhone’s firmware so that you can get access to the internals of its operating system and therefore allowing you to install many other  third-party applications that are not available on the App Store on your iPhone.

Jailbreaking your iPhone doesn’t make very much of a difference in the operation  part of it. But it does gives you a new meaning to owning an iPhone. Thanks to all the developers.

The good thing about jailbreaking is that there are many useful and interesting applications available through other channels available to you that will never make it to the App Store due to SDK restrictions.

The bad thing to it is that it makes people think that their warranty will be void if they jailbreak their iPhone. While it may be true that your warranty would be void if you send a jailbreaked iPhone to Apple for repair, you can actually restore your iPhone to factory default before sending it to Apple.

Many people are very sceptical about doing it as they are not familiar with the whole process. During the OS 1.0 -2.0 days, I would admit that it’s a hassle to do a jailbreak and iBrick (meaning your iPhone is bricked and cannot work anymore), is often heard of and a majjor concern. But the jailbreak for OS 3.0 and above has been super easy and I have not met any unsuccessful attempts since doing it. To jailbreak your iPhone, click here to read my other post.

To date, I have jailbreaked about 10-15 iPhones on OS3.1.3. Many of my friends can’t believe that its that simple. Done in a matter of minutes and a couple of clicks. Those who have jailbreaked will never look back. OS4? I will wait till its jailbreaked before upgrading!
