If you are unsure of what you are getting into, stop while you are ahead. Many people have tried breaking out the old Torx head screwdrivers and playing to get their mods looking sharp. However, there are some little things inside the units you need to know about or else you'll end up regreting your attempt later. The biggest of which is the ribbon cable going from the keypad body to the flip. Some people pinch these off when changing the parts resulting in the external panel doing crazy things. You can also shatter the LCD displays if you are not careful in your reassembly efforts.
