Yeah true. As far as I know, I can't produce a file for iPhones. Apps have to be downloaded through the App store, right? I doubt very much a game with this much nudity will pass the app store's rigorous scrutiny!
Well, you can sign apps using third party certificates, or just distribute the IPA (people can sign it for themselves using a free apple developer account) However you NEED a mac to develop for iOS because XCode is for macs not windows!
That's fine, I have a Mac & have created apps for the Apple app store before. It was a lot more complicated than creating an Android app but possible. The only problem is that I can't see a way of distributing it without using the app store.
