Is it possible to write applications for the iPod and iPod Nano platforms, i.e. not iPhone / iPod Touch?
Some iPod 'Click Wheel' games are available on iTunes, but I can't find any developer documentation.
I believe game publishers had to work directly with Apple on "classic" iPod applications - here's an article with an EA dev.
Our talented teams here at EA Mobile first develop the games and then we work with Apple to do the final integration and testing on the iPod. To get ready for the launch, some of us practically lived in Cupertino. We even had to maintain the same level of secrecy while we were at Apple headquarters.
