There is a GameCola app for browsing GameCola content from your Nokia phone available in Nokia’s Ovi Store. I know the Ovi Store attributes the app to me, but I used a widgety-app-generaty-thing to make it, so it’s somewhat basic. That said, if it looks like people like it/like the idea of it, I may spend the time to develop a proper Android/Maemo/Meego app for GameCola.
In any case, the app is available here.
Why not have a mobile version of the website?
