Please anyone can tell me if Unity 3.x still free & how I can get the free license & can I get this 3.x version Now for free ?
Unity 3 is free, while Unity 3 Pro and the platform add-ons such as Unity 3 iPhone cost money. The division is the same as it is/was with Unity 2.
When Unity 3 is released, the free version will be available for download.
Until Unity 3 is released, pre-release versions are only given to people who have bought the Pro version or other paid versions, so you can't have a pre-release version of Unity 3 for free. You will have to wait until Unity 3 is released.
