The LED is obviously multitalented because it displays both green and red like you said but I think making such a change is a complicated matter that is probably (my guess) only achievable through software manipulation - the LED is programmed to turn red under certain situations, like when the charger is plugged in and the phone is off or when the battery is low but I don't know how this can be done otherwise...

Pretty interesting thought though...

I believe you can invert the colors of the green led so that it will blink red when on and turn green when charging just by changing the pools of the two legs on the LED (turning it 90 degrees around on the PCB).

to Mimzo, frost and yapliren

Just a little more technical answer to your little chat about the red, green and blue LED. The fact is that the green/red LED is the same component, however there is two different colours "inside" (red and well...green). The way it works is actually like a diode (semiconductor) and if you pass a current trough the diode it will lit up in either red or green (because of the small x-tal inside). The colour depends on which "leg" on the component you connect to the the voltage/current source. However some red/green LED only have two "legs" and if the current/voltage is giong one way it will lit up in red but if the voltage is reversed, it will lit up in green colour.
On the 3 "leg" LED you can even get an orange colour, by applying voltage/current to both parts of the LED at the same time.
Anyway, if you want to get an red colour instead of the green colour it might be that you just could turn the LED opposit, however if you do so you have to take into consideration that the green LED might(this is quit normal by LED's) draw a higher current than the red LED and therefore the circuit which drives the LED (the driver or resistor or whatever SE have used) might not be designed to do so and this will (if you are VERY unlucky) burn the circuit.
Further to this I can inform you that if you want to change the green/red LED to a blue colour, then you have to notice that blue LED's as a common rule is drawing a much higher current than both the red and the green LED, and then the above might also happen. And further to this the battry will go dead quicker than normal.
Well this was the booooooorring technical details about the LED's, but I sure agree with you that the blue is MUUUCH nicer that the red and green LED.

Thanks for the insight - very useful piece of information there on the LEDs.
