Now, we can make apps designed for the iPhone instead of the iPad /really/ work in full screen instead of that awful quasi-thing that apple came up with! You of course have to first be jailbroken.
Using SSH or your favorite USB Browser. Make sure you have afc2add installed from cydia or rock.
1.) Navigate to the app you want to make compatible in /var/mobile/Applications
2.) Open the info.plist in the applications main folder (TIP: we recommend you just use ifile from Cydia to do the editing)
3.) Add the following commands :
UIDeviceFamily

1
2



Respring and then you should have a nice iPad size app 

Thanks to JStraitiff, look forward to a more automated solution at some point in the future.
