Correct. Note, however, that the plan is for Unity and Unity iPhone to be merged into one application in the future. The only reason they are two distinct apps at the moment is because it was easier and faster to fork Unity in order to get the iPhone functionality out there and working well as soon as possible (Unity iPhone is basically Unity 2.1 with added iPhone stuff). From a licensing standpoint, on the other hand, Unity iPhone can be considered as a plug-in. So yes there is a bit of a disconnect between the licensing and the reality right now, but that won’t last.
Yep the upgrade path seems to be: we all need to own Unity Pro licenses. But for now Unity iPhone 1.5 seems to work fine “standalone” for owners of Unity 2.x Indie.
Awesome my Unity 2.6 download just finished
I’m very new to this whole programing thing and I’m kind of glad to hear that UNITY3D is now free- (they must be making tons of money on iphone alone)- but… how hard is it to port a game from UNITY3D to UNITY iphone?
Probably very difficult, because Unity3D is an engine that powers World War II Online and is not available to the public as far as I know. But porting a Unity game to Unity iPhone ranges from very easy to fairly hard, depending on what language you use, what features you’re using, the scope of the game, the kind of assets you’re using, etc. If you start with the plan of having a game work both in Unity and Unity iPhone and understand the limitations of the latter, then it’s pretty simple, otherwise maybe not so much.
