I see two options for you,
Shiva 3d allows you to develop the game on PC, but you can build it for iOS only on a Mac with the authoring tool. You can use MacInCloud which allows you to build your application on a Mac. Totally legal.
Or you could wait for Leadwerks 3.0 to come out with iOS and Android support, you could do the same thing with MacInCloud. No hackontosh required.
