YouTube user PSPfano has posted a video of GarageBand for iPad running on an iPhone 4.



From TUAW:

He accomplished this by using a hack (detailed on 9to5) which allows users to modify jailbroken iPhones and allows them to run most iPad apps on them. After applying the hack, PSPfano moved the GarageBand for iPad app with altered metadata to an iPhone 4 via OpenSSH.
