Apple has started counting down to 25 billion app downloads across the iPhone, iPad, and iPod Touch. Apple hit 15 billion downloads in early July. What this means is that between then and now, Apple had been averaging about 1.5 billion downloads per month. The person that downloads the 25 billionth app will receive a $10,000 gift card for the app store. Apple has paid out over $4 billion to app developers thus far.
