Is it possible to build on an Ipod Touch? I thought that it was, because I watched the introduction video online before the SDK came out. However, I can't remember if they said that you are only able to do it on an Iphone or not. If you can then do I need to pay the $99 developer fee? Or can I do it without paying the $99? Because like in the video they said that they povided (this...this... and this) for their "paid developers." If anyone can answer these questions it will be greatly appreciated.
