Question on Unity 3D update to 3.0 ...

I'm thinking about buying Unity iPhone right now becauseof the discounted price but I have a question on the 3.0 update and the affect on Unity iPhone:

Will the Unity 3D 3.0 update affect all unity things( iPhone, Android, Web Games) or will it only affect the web games part.

--Because if this updates iPhone and I buy iphone now that would waste me $500 dollars (updating cost).

All the unity versions will be updated

I.e. - if you have a license for unity 3.0 iphone, it'll be updated to 3.0 along with the pc/mac version and anything else you have a license for when 3.0 gets released.

You wouldn't be wasting money at all
