buy older version of unity iPhone for making free games on iPhone

hello
i want to start using Unity for iPhone, but at this time I’m not albe to pay $400 for the full Unity3 iOS app
now, is there any way i can buy the older version at a discount price ? (1.6 or 2.0 if it exists)
its just for making some free or maybe a very cheap game

I’m aware there is a demo, but its only for 1 month and I’m not legally allowed to publish a game with that
and i really want to do this legally

thanks

Unity iPhone is no longer available. At this point you really wouldn’t want to use it anyway; it’s just hopelessly outdated compared to Unity 3.
