Mobile app development can, without question, be a lucrative professional endeavor, at least for those with the skill and creativity to develop that which mobile users want in big numbers.

This week, Research in Motion revealed just how lucrative app development has proven to be for 13% of its publishers. According to RIM's vice president of developer relations, Alec Saunders, that's the percentage of BlackBerry app devs who earn upwards of $100,000 annually developing apps for BlackBerry App World.

The news is, naturally, surprising to some. Although BlackBerry's app storefront is less profitable that Apple's App Store, it's still a bigger cash cow than Google's Android Market. Of course, when you begin to plunge into the numbers to see which platform's developers are truly making the most money, the facts start to get a little hazy.

RIM today said that it now has 60,000 apps in its App World applications storefront—still miniscule compared to the millions that live collectively on the Android Market and Apple’s App Store—but a significant improvement on the 17,000 that were in App World last January. Collectively, the store has seen 2 billion downloads as of last month, with 6 million downloads per day.
While BlackBerry continues to struggle and perpetually lose more and more of its smartphone market share to iOS and Android-powered devices, RIM maintains that its developers make excellent money in large part because they aren't "hobbyists" like many of iOS and Android developers reportedly are.
