Apple has fixed what it once described as a “minor glitch” that kept iPhone developers from issuing promo codes for apps carrying a 17+ rating. iLounge reported in December that developers were unable to issue codes for adult-rated apps, which limited the promotional avenues available to such applications. At the time, we questioned whether the problem was due to an Apple attempt to limit promotion of 17+ titles, or a temporary bug that would be resolved in time. In any case, the company took over six months to fix the “glitch.”
