here is a standard iphone, notice how it only has 4 on the dock and 4 columns for apps. Also its bland and boring.
here is a quick snap of one of my pages on my iphone, notice the custom background, 5 icon dock, 5 rows of apps. Also there are a bevy of applications that just aren't available on App store. Also unlocking/jb allows me to use my UK T-mobile SIM card while I am here so I still have a phone.
