I spotted this in Cydia the other day. It's from the same people that developed FullForce (that allowed iPhone only apps to run on iPad without using the 2x simulator and looking like shit). There's not many apps I'm that arsed about but there is one particular one I like to run in full screen and RetinaPad does it very well.
Review of sorts HERE - this bloke reckons it runs iPhone games in full screen quite well.
