How To Use Cydia, The other App Store

When you jailbreak your phone you get access to Cydia, the iOS app store that exists outside of Apple's reach.

There are a number of cool apps and tweaks available there, from apps that turns your phone into a WiFi hotspot to tools that let you completely customize your iPhone's interface.
It can be a little daunting at first, especially if you're only familiar with Apple's App Store. Here's a tour on how to install and uninstall apps from Cydia.
