iphone-only app on an ipad needs ipad launch images

while making an update to my iphone-only app (it is not universal) for ios7, i noticed two things. first, the app automatically filled the screen of the ipad - there was no button in the lower right corner to toggle the size from 1x to 2x. second, when the app was launching, the launch image was getting pixelated. the solution is to include the appropriate launch images for ipad.
