Since my only iOS project is a single-developer one, I plan on refactoring into Xcode 4, since it lets me rethink how I structure the app. I never did a Universal iOS build of the app that I work on because I got frustrated with making it work in Xcode 3 -- it's worlds easier in 4 (if there is a better word for worlds there, use that one instead. you have no idea how much better).

I simply cannot sing the praises of how much sense Workspaces make, especially when dealing with a Universal iOS app. As a recovering Visual Studio user, they were the feature I was genuinely looking for in Xcode.

You might want to take that approach...Xcode 4 in developer preview seemed to misbehave if I imported a 3.2 project, but that could be because it was developer preview.
