Thanks to Macworld's iPhone Central, we learn today that Apple has purchased full-page ads in both the New York Times and the Wall Street Journal that include the news - in small print at the bottom of the ads - that the iTunes App Store has now distributed "over 300 million" iPhone apps from a total of "over 10,000" titles available.

You'll notice that we said "distributed", not "sold", seeing as how Apple's ads don't distinguish between paid and free apps - and free apps are understandably a high percentage of their offerings.

Still, the 300m and 10,000 figures are a substantial increase from the 200m apps distributed and 5550 apps offered cited by Steve Jobs during Apple's October 21 fourth-quarter earnings conference call.

No matter how you slice it, those 300 million must include a ton of downloads of The Blimp Pilots' Koi Pond, the most popular paid app, and Pandora Media's Pandora Radio, the most popular free app in Apple's list of the top 25 paid and free apps from the iTunes App Store. ®
