A few weeks ago, some jailbreakers devised an effective, if slightly daunting, way to force iPhone apps to fill the iPad's screen. Now, there's a jailbreak app that does the same, and the results are incredible.
The app - technically an OS extension - is called FullForce, and it's available in the Cydia store for free. (If you're not familiar with jailbreaking and Cydia, check our guide here.) The app's settings are controlled via a panel in your system settings app, which contains toggle switches for every iPhone-sized app installed on your iPad.
Using FullForce is a much simpler process than the old method to force app scaling, which involves editing a text file packaged with each app via SSH, but the results aren't perfect: Most scaled apps contained slight formatting oddities, and some don't scale at all, like 3D games. That said, a few vital apps scale really well - the NYTimes app, which has waaaaay more content than the iPad version, fills the screen without a problem, and the Facebook app - where is that official iPad Facebook app, anyway? - is good enough to justify jailbreaking on its own.
