Sorry it took little longer than expected, run in some issues with cupcake (SDK 1.5)
I have attached a Demo project for all interested with some screenshots and modified .project for TabWidget Project(fixes cupcake problem ref http://groups.google.com/group/android-developers/browse_thread/thread/5537ae10e4143240) if you use eclipse.
1. My env:
Eclipse Version: 3.4.2
Android SDK 1.5
2.After you import the TabWidgedDemo project you will probably need to fix your buildpath.
Make sure to add TabWidet as a reference to TabWidgedDemo.
3.In TabWidged project you will need to update the .project file otherwise you will get Verify error when deploying to the device.
If you have any questions let me know, I hope you enjoy the project, more improvements to come
