PhoneGap is an open source tool that allows developers to build mobile apps using HTML, CSS, and JavaScript instead of native languages like Objective-C or Java. It wraps the web view container to give apps access to device features like geolocation and accelerometers. While documentation is still maturing and bugs may exist, PhoneGap is free, open source, and offers developers a way to create cross-platform mobile apps without having to learn multiple programming languages. Sample PhoneGap apps and getting started resources are provided.
