There have been numerous complaints from iPhone developers about Apple prohibiting the use of promo codes for applications commanding a 17+ rating as 17+ rated apps don’t just consist of adult apps and violent apps.
According to an article on pcworld, Apple has now done a complete turnabout on the 17+ promo codes prohibiting and is again issuing promo codes to17+ rated applications.
This can only mean that Apple has been listening to the developer community and has realised the error of their ways and made a quick about turn to appease irate developers.
