Hi…
May be i missunderstand, but i read in some place that there is an Android free version, is that true?..
There was a 3.x basic android and iphone license giveaway but it’s long over.
ahhhh 
I made a wish on unity feedback asking for free android creation so if you vote for my wish you may get some luck
Good luck with that. They made Android and iOS licenses free to boost upgrade sales for Unity 4. Now that you can’t buy Unity 3 anymore, there is no reason for them to make it free. There’s an extremely low likelihood it will happen again. You unfortunately missed it, but it won’t come back just because of a post on the wishlist forum.
EDIT: By the way, welcome to the forums. I apologize for sounding harsh, but the request has been made multiple times.
Yet another reason to keep an eye on Unity Gossip 
Thats where I got the news.
