How to buy Unity3D Pro

Hi,I come from china and want to know how to buy Unity3D.(1)I was thought I will buy Unity3D Pro + Android Pro(it will cost me $3000)and later when I finish build APK for Android then I will buy Unity3D Pro + IOS Pro(it will cose me $3000).Total it will cost me $3000+$3000=$6000(If when I buy IOS Pro I do not need buy Unity3D Pro anymore?).(2)For saving money,I will buy Unity Pro+ Android Pro +IOS Pro = $4500 at one time. And my team has two people,should I buy “Team License”.

Anyone can help me,Thanks!

So you can buy the IOS add on to your initial Pro + Android at any time for another $1500, you don’t have to buy them at the same time.

If there are two people in your team then you need to buy two licenses of everything however! Unless one person will develop droid and the other iOS versions. In my team of 3 we have iOS for everyone and Droid just for one programmer and our continuous integration build server.

I recommend Team License if you will switch often between Droid and iOS then the Asset Cache Server is a real help. Asset Server itself has some very annoying things, but generally works and I believe version control is a requirement for just about every project.
