Do I get any performance or visual benefits on the games I develop if I choose Unity Pro and iPhone Advanced and not Indie and iPhone Basic?
You can get smaller build sizes with Advanced, but it appears the scripting, rendering, and physics are all the same:
Hi,
mindlube, can you explain some more informations about the diffrence during the development. Is this so much better from performance or other stuff ?
greetings

Sorry I am understanding the question 
The link I posted above tells the differences. The performance should be the same for Standard vs. Advanced, except for possibly smaller distribution/download size and a custom splash screen with Advanced. I am using indie + iphone standard.
Right now there aren’t too many differences (main are the ones mentioned + networking. Basic only has the WWW class, no sockets or anything) yet, but over time, Advanced will be getting more and more powerfull features needed by professional devs.
