How do you go about changing the Battery Icon, Dialer, Keyboard, Calculator without using Customize? Can I just go into the phone using SSH and CuteFTP Pro and manually replace the contents of each folder that corresponds with the item (Springboard.app, MobilePhone.app, Calculator.app, UIKit.framework)... or will that total screw up the iPhone? If so, do I replace only the contents of the new stuff or replace everything in the master folder with new folder? In other words... the new Retro Phone Dialer has 15 components, while the original MobilePhone.app folder has 60 components and 4 language folders. Do I only use the 15 from the new dialer or just replace MobilePhone.app completely?
