Hi ok so I have a iPhone 4, im greedy I want it faster! So I read stuff about no background on the iPhone 3G did help with speed alot, so I edited the N90AP.plist in the SpringBoard.app folder so I do not use backgrounds. It seems to run faster, dos anyone know what the "venice" key is for? I would try it but I am about to go to Night Of Joy, Disney World. So I do not want to brick my iPhone right before the trip. Any help?
