If you are looking to take full advantage of your jailbroken iPad 2 running Safari, this is definitely the Cydia tweak for you. FullScreen For iPad is much more than the title states, as it turns Safari on your iPad into a real multitouch browser. There are half a dozen different gestures that you can set, along with a shake to toggle setting that allows a senstivity adjustable shake set to an action in Safari.
This is a Cydia tweak for your iPad and does not install a new app to your homescreen. Customize your preferences in the Settings app under the extension for your iPad.
FullScreen for iPad is available for $1.99 from the ModMyi repo in Cydia.
