Hey Cupa T, you don't sound daft at all. Ok did you find the app on the Android Market on the phone? If yes, then did you click install, bottom left of screen? Once it is installed it should be in your app drawer on the very last screen so keep swiping right to left til you see it. Its a blue speech bubble looking thing.
I have now got an X8 on test and its basically the same as the mini's, so I then arranged icons on dragged it to one of my corners as this is the app I use the most.
Let me know how you are getting on and if you need anything else. Don't be worried about asking, its the only way to find out when you are a bit lost.
