New day, new app in Cydia: FullForce. This only works on the iPad, and using this app you can force selected apps to show in fullscreen iPad mode, even if the developer hasn’t certified them as compatible. If you prefer to do it manually ( I’m sure you do… ) you can check our tutorial. Also you can check the list of iPad compatible apps here…
Later edit:
FSM EXCLUSIVE DEAL Keep in mind that both methods ( Cydia app and manual way ) are here just to get you drunk with cold water. If you double the size of apps, the touch zones are redrawn in all the wrong places and some apps might not even render or just crash…
Ohhh, and by the way… Full Force won’t “just work”. You will have to set toggles in Settings.app
