Yeah, I was once intrested in making iPhone games but the SDK was only available for Mac. Plus I don't really have a lot of programming knowledge so I can create a whole game on my own.
Are you sure it was for Far Cry 2 and not Far Cry 1? There is no SDK for Far Cry 2 and I don't think the community was able to fix any of the gameplay issues like the rapidly respawning guard posts.
