You've already jailbroken your iPad 2 using pod2g's exploit, but what should you do with it now? For starters you can add basic iPhone apps that Apple didn't include with their tablets for some unknown reason.
iOS developer Ryan Petrich's Belfry tweak allows you to add Clock, Voice Memos, Stocks, Calculator, Compass and Weather to the iPad. Both the Clock and Stock apps work with the iPad's native resolution, but the rest must be zoomed in to work better with its display.
The Belfry project is available for free in Cydia from the BigBoss repository.
