Is there really a patch for this?

A friend of mine told me that somewhere there was a patch that can turn the illumination of the phone keyboard from white to blue. I have a W580i and hate the boring white LEDs, and have searched for hours trying to find it, but have had no luck. Anyone else know of such a patch, for ANY phone type or firmware? Thanks

how should one do with a patch of white LEDs blue tint? knew not how to proceed without the exchange of LEDs

there is no way you can do it

Unless the leds are di-color, you can't do that.
