Betavine is an open community and resource website, created and managed by Vodafone Group R&D, for the mobile development community in order to support and stimulate the development of new applications for mobile and Internet communications. The Betavine website allows developers to upload and profile their alpha-stage and beta-stage applications, provides interaction tools for members to share knowledge and give feedback on apps, and discuss topics in mobile. Betavine also contains a growing resources section with technical topics and APIs.
The Betavine website was built using open source components so there are a number of resources for open source in mobile - such as the Betavine Forge where developers can share code snippets, post projects, and collaborate on projects. The recently publicised Vodafone Mobile Connect Card Driver for Linux is hosted here, for example.
