This video is educational purposes only. Its the same as using other cydia repos to get what you want and tryout, then purchase them. Like I stated in the video this i just to give you a feel to what you will purchase. I love android and google and i loved how the play store gave you time for a refund if things didnt work out for you. I wish apple did this. but they don't. so check out the vid.
