To support OS 3.x, please set Base SDK to iPhone Device 4.0 and iPhone OS Deployment Target to iPhone OS 3.x. Extra linker flags may be needed if NSConcreteGlobalBlock and UIBackgroundTaskInvalid runtime error occur under 3.x.
The linker flags are:
-weak_framework UIKit
-weak_library /usr/lib/libSystem.B.dylib
