You need to setup the app to build as follows:

• Base SDK: iPhone Device 4.0
• iPhone OS Deployment Target: iPhone OS 3.0

They are two separate settings when in the Project > Edit Project Settings section of Xcode.

Hope that helps!

In your 'Info.plist', add 'Application does not run in background' and make sure the checkbox is NOT checked.
