Click on the �Download� button and then wait until the download completes. Sometimes you will receive a message at the end that prompts you to reboot your BlackBerry. If you get this, select �Reboot�.
So that�s it! The software has now been installed on your BlackBerry. Unlike installing software on your PC where you have to first download it, then install it, BlackBerry software automatically installs itself.
Ok, so those are OTA downloads. What happens after the download completes? You should have an icon on your home screen for the app. But I haven't used either, so I'm only able to give you generic support. You might try searching the forum for Vlingo and Phoneface to see what results other users are getting. Sorry I can't be more help.
