Thanks for the explanation. My problem is this: Paid apps you have to pay anyway. Without paying you can not download. If you've paid. then you have the full version and you have no problem. And if you have to pay what is the usefulness of these apps. Or I understand wrong. I still do not understand. All I know it very useful apps, but I could still nothing.
Well you can always download the apk of the paid app, for free, if you look hard enough. That's where the patched GooglePlay becomes useful.
