Unity 3 Upgrade Pricing Problem

I just tried to upgrade to Unity 3.x Pro with iPhone Advanced and have hit a bit of a problem.

I have a Unity 3.x Pro key, when I try to upgrade to iPhone advanced it costs $1200.

I also have a Unity 2.6 with iPhone Advanced key and when I try to upgrade with this it costs $500… BUT it also wants to charge me another $500 for Unity Pro 3.x which I already have!

Given that I already have Pro 3.x and iPhone Advanced 1.x, is there a way to buy just iPhone Advanced for 3.x?

contact the support through mail, tell them you would like to upgrade and mention the license key of your U3 license and the U2.6 + iphone advanced assuming you upgraded your U3 from that.

otherwise you will likely lose one of the two, cause the addon is bound to the base license

had to do this myself and it went all fine
