An unusually large number of the developers at last week's WWDC in San Francisco may have been Android supporters, according to a survey conducted by Piper Jaffray analyst Gene Munster. Of 45 developers, 47 percent indicated that they were currently coding for Android alongside iOS. While everyone polled was developing for iOS, only 36 percent said they were coding for no other platforms. Android's popularity was followed by BlackBerry at 36 percent, Windows Phone at 13 percent, webOS at 7 percent and Symbian at 4 percent.
