Well some good news. The Casio G-Shock iPhone application which was available on the Japanese iTunes is now available on the American iTunes. I have downloaded the application and have to say that I have mixed feelings about it.
The games can can long in the tooth, but you do get 'rewarded'. You get new models and movies. The new models that you get can be used as the watch on the main page to show the time, day, date and month. Try it out as it is free. Anyway it is great to see the application be made available outside Japan.
The games. You may want to reduce the volume as the games can be loud.
Your collection of G-Shocks.
