I have two questions: -Does anyone know if the backlight on the iphone is the LED or CFL tube type? I would feel better leaving the screen on for long amounts of time if it is the LED type. -I noticed if I leave a google talk or AIM running all day while its charging the backlight dims and then shuts off. Is the only way to keep it on while charging to set the sleep time to off? The problem with this is that if it is accidently turned on while in my work bad it will never turn itself off unless I set the sleep time back to 1 minute.
