Well that shows that you don't know much about JailBreak. Maybe just search for Flex 2 and see what you can do to individual 3rd party apps, you can particularly control the apps, and return certain function's values (force them).
Here are my somewhat ESSENTIAL cydia tweaks that I must have almost every time I get a new iPhone:
Action Menu
Activator
Barrel
Bolt
Bridge
CCClockOpenToAlarm
CCToggles
Coono
f.lux
Flex 2
iFile
iTouchSecure
iWhiteBoard
MultiIconMover
MultitaskingGestures (previously zephyr)
NCObay
ProTube
SpotDefine
Springtomize 3
StatusModifier
SwipeSelection
TabLess
TransparentVolume
