It was pretty straight forward to put it up on iTunes. The hardest part for me was to have all provisioningprofiles and certificates working as they should to only be able to build and test the game at first. It was quite confusing, Apple could have done that process much easier.
I'm on PC and that made everything a bit harder, but a friend helped me with some critical Mac-specific parts.
They (iTunes) said nothing about the content and I wasn't worried because all content is our own original content. I pick the price and I think you are totally free to set what ever price you think is best. Thanks for the idéa I may do so in the future, I'm absolutly shure they would allow that, it's good for them as well, they keep ~35% of the revenue.
