Once you’ve hacked your iPhone, you’ll notice a new icon on the home screen called Cydia. This is the jailbreak version of the iPhone’s app store where all the programs that aren’t officially supported by Apple live are available. This is where all the effort in jailbreaking the iPhone becomes worthwhile.

Before you look through Cydia for some weird and wonderful applications, there are a few things worth mentioning.

First off, don’t assume that all the programs are free because they’re not in the App Store. Many of the best applications are available as trials and require you to pay a licensing fee over PayPal to continue using after the trial period expires.

Second, since there is no approval process for Cydia applications, there is no guarantee they won’t slow down your iPhone or cause other stability issues. Be wise when choosing applications, as Apple won’t fix your hacked iPhone, especially not under warranty.
