In learning about development for the BlackBerry platforms, we have to create a build for each phone and each network. As a developer, I just can’t afford it. Most of my customers right now have BlackBerries. I think that in the next year or two they will have an iPhone. I am already hearing word that a few senior executives are asking the IT departments to check it out. We should be one of the first “Real” Enterprise developers who have a native iPhone application.
