1059 Apple Mach-O Linker warnings in xcode

I don't know if these warnings are an issue - the game builds and runs on my iPad - but of course I would rather not see them. How can I get rid of them?

Here are the build settings:

Unity 3.3

xcode 4.0.2

Target Device : iPad Only

Target Platform : Universal

Target iOS Version : 4.2

iPad is running 4.3.3

All the warnings are "Apple Mach-O Linker warnings" about ARM functions not being 4-byte aligned.

Bonus question : are there any guidelines on which iOS version to target? Should our games always target the latest major?


A little more searching and I found it on the forum: http://forum.unity3d.com/threads/82827-Apple-Mach-O-Linker-Warning

So I guess it's not really a problem right now

I had the same problem.
I made a video to show you how to fix it.
