You see PhoneGap. You heard people talk about it. You know you want to try this amazing platform which allow you to build cross-platform mobile application with one code-based.
At the moment, PhoneGap is updated to 2.0, more powerful, less bug, and has a good opportunities to expand its border to iOS6 and Windows Phone 8.(Android already on the way!)
But as I was a beginner, I think you need a good tutorial to follow, specifically, the video, which you can pause to follow the step and replay again to find out what you may missed.
So I would like to suggest you to Piotr’s video about how to create your project on iOS and Android with PhoneGap 2.0.
Happy Phonegap!
