I came across this video on YouTube and found it very interesting. As a lot of South African's and other people from around the world question why should we jailbreak our iPhones.

This video is done by Scobleizer and it features Jay Freeman and Britta Gustafson. Jay Freeman is the well known creator for the Cydia App Store which is the alternative of the iTunes App Store. Cydia has many third party tweaks, apps and themes to download! 

Jay shows different tweaks he has installed to enhance his iPhone experience through Cydia. These are the tweaks:

FiveIconDock - lets you put 5 icons in the dock instead of 4
qTweeter? - status bar tweeting
Graviboard - adds gravity effect on your icons
Iconoclasm - icon layouts
Springtomizer - Change slide to unlock text & others
SBsettings - status bar hot key toggles
Barrel 1/2 - Homescreen scroll effects
