Apple's army of mobile developers is loyal to iOS, but nearly half of them are two-timing with Android and there are significant subsets playing with Research in Motion's BlackBerry platform, according to a Piper Jaffray survey.
This survey, which was in a research report on Monday, isn't exactly scientific. Piper Jaffray analyst Gene Munster surveyed 45 developers at Apple's WWDC conference. Naturally, Munster was going to find a lot of iOS fans.
However, if you look at the data below there are openings for other platforms. For instance, 11 percent of developers complained about Apple's approval process for apps and another 38 percent had a beef with strict limitations.
Those issues have translated into interest in Android. In fact, 47 percent of developers said they also make apps for Android---even though iOS is better for monetization---and 36 percent also developed for RIM. A 13 percent chunk of developers also developed for Windows Phone 7. Keep in mind this poll was conducted at WWDC.
Add it up and iOS dominates with developers---at least at WWDC---but even with the home field advantage there are some small cracks for rival mobile platforms to exploit.
