As rckt26 has stated, those threads are about making purchases. We need to be able to Restore Purchases as it is a iOS Requirement for Non-Consumable IAPs. As this is the only thing for me to do to be able to release my game, i cannot wait until 4.9 for this functionality. This is why I need to know if it is making 4.8 or not (as of preview 2 still not implemented). As I am very busy, it would be nice to know in case I have to commit the time to getting it figured out via C++. (already spent some time looking into it last week, more details in my AH question)
Here is the link to my AH from a few days ago.
