After updating to iOS 7 and repairing my broken screen, every time I launch any of these apps, they show in the middle of the screen. And touch won't work around it. I googled and saw a post that says; using a tweak on Cydia will make them work smoothly. So I jailbroken my iPhone 4S because of that, after all the JB processes, when I launch Cydia too, it doesn't show in Full Screen. Every other apps work smoothly ! But I need these 2 apps, most especially the FB App. Besides, I need to access Cydia tweaks, because my Chipped iPhone 4S doesn't have 3G/EDGE toggle which makes my iPhone to always be on 3G and drains battery faster. Kindly help a brother, thanks Guys.
