When on your mobile device, go to the respective store and search "SlingPlayer for [Enter Mobile device type here] free". The search options should show both the paid version, and the free version. Below I have links for 3 articles that will explain how install the application:
- Slingbox.com - How to buy and install SlingPlayer for Android
- Slingbox.com - Uninstall and reinstall of SlingPlayer iPad and iPhone
Hope this helps!
