Rebound from @Regy Perlera awesome presentation templates. You download the free After Effects Template here: http://uxinmotion.net/content/ipad-03/
Download includes 5 render presets including a special one I made for the Dribbble community at 800 x 600. It's all drag and drop so once you create a cool screen animation in After Effects, import this, swap a single layer (instructions and video instructions included in above link) and you're good to go!
