With the help of Erel's tutorial for inapp billing v3., i have managed to make it work. I have a question. In the market i have 2 version of my apps. One is lite version (with no preium features ) and one is the pro version which is paid.

I have implemented the inapp billing for lite version and when inapp purchase complete i make my lite version to unlock all the features that pro version has. No problems until here.

My question is when the user upgrade to pro version via inapp purchase(in fact still using lite version but with unlocked features) , i want to make it impossible to same user buy the pro version in the market ( i know he will not buy the pro version again but it is possible because they are different apps ).
is it possible ?
