Note: you need to weak-link UIKit.

This probably won't crash, but it's worth noting that setStatusBarHidden:withAnimation: doesn't take a BOOL as its second argument, it takes a UIStatusBarAnimation enum value.

The TTOSVersion() isn't so trustable to get the current version. This solution from Matt Gallagher seems to bem more "secure": http://cocoawithlove.com/2010/07/tips-tricks-for-conditional-ios3-ios32.html. I do some correction and commit on my fork. Maybe we can merge the changes.http://github.com/seqoy/three20/commit/23354862690c8f7e0c18d8c1f937ace420a18a67
