Just wanted to share that some weeks ago I published a free pocket reference for mobile phones. It contains the whole basic language as well as all the libraries that comes with the Arduino software. It also contains a handy resistor-calculator. You can find more info here: http://www.flashgamer.com/apps/
The app is free and will always remain free.
I hope some of you find use for the app and that you like it!
My plan is to maybe also make a "pro" version (if I have the time for it) and that would be something like a dollar. That would contain additional content such as a hardware reference with lots of images and examples, as well as several more useful calculators. No idea when I'll get around to do this though as this is just a hobby for me.
