This frees the user to do things not normally possible on your standard iOS device, such as sideload non-App Store apps, install mods, use custom themes, add new widgets to your home screen, set new default apps, and tons more.

You should take extra caution when considering a new app or mod to download on a jailbroken iPhone or iPad.

Launch the Cydia app from your home screen, and then scroll through and find the apps, themes, and mods you want to install.

Most of these are optional ways to customize the look and feel of your iPhone, but there are a few that you should download so you can get the full benefits of jailbreaking your device.
