Unity iOS and windows

I was wondering why I can’t use the iOS features under windows? I am not expecting a full compatibility (create projects or compile). But it would be great if i could set the screen resolution to the iPhone resolution, also be able to access the settings for iOS under windows, and graphics emulation.

I would need this since I do all my graphics under windows (3ds max, photoshop, mudbox)

Just do a custom resolution under per-platform setting
