Restore seems to work fine for me, but I cannot tell when all purchases made by the user have been restored.

Seems like we need a call back when this occurs. The iOS Reference Library talks about this method that gets called:

paymentQueueRestoreCompletedTransactionsFinished

Is that implemented? I may just be overlooking something obvious (if so, sorry), but I need to do some processing when the restores have finished.

Thanks,

Paul
