I do not have access to a MacOS box. Everything I've found while researching iPhone development leads me to believe that you have to have one to develop for the iPhone. I have a Windows 7 development box running Visual Studio 2010 with IIS 6.0 in the background. I need to develop an App. Can I create an icon-on-the-desktop-out-of-the-browser App with only HTML5, Javascript, and CSS3? Can I do it without MacOS and Objective-C? Most importantly, can I do it without spending hundreds of dollars or man hours?

I will simplify my question: Can I develop an IIS web application that can be used out-of-browser on an iPhone?

Does PhoneGap.com create native iPhone apps?
