and notice that pin 10 (not documented in the manual) is the backlight led controll, so if you send diferent values of PWM to that pin you can dim the backlight.
Are you referring to this ethernet following shield?http://arduino.cc/en/Main/ArduinoEthernetShieldI didn't see they refer to analog 0 and 1. What exactly do these two pins do on the ethernet shield?I am working on my Phi-1 shield's revision. The new shield should be compatible with ethernet shield
Finally I found a solution: Cut pin 10 from the LCD. But you can preserve the shield. Have a look at: http://hajos-kontrapunkte.blogspot.com/2011/02/arduino-tower-of-babylon.html
