Yes, support package will allow you to use most of the fragment widgets back to Android 1.6. With NineOldDroids (http://nineoldandroids.com/) and other packages such as ActionBarSherlock (http://actionbarsherlock.com/) from the same developer, you can get a lot of the goodies from ICS and above to work on old Android devices.

All you have to do is to import the compatibility libraries. The way they work is that for the new devices, they will use official Android API, for the old ones, they will simulate and run them in compatible ways, so things may look different.
