Apple has put a stop to iAd placements in kids' apps, a developer informs. Mike Zornek -- creator of the Dex Pokèmon browser for iPhones and iPods -- notes that last Thursday, his iAd fill rate dropped to an "awful" 5 percent. The next day the rate fell to zero, persisting through Saturday. This prompted Zornek to email Apple, and also to post a question in Apple's developer forums. On Tuesday he received a response.
