Joey is Mozilla's answer to the mobile browsing problem: too much data necessary for download, poor accessibility to the data and the lack of formatting the content for the phone. "Project Joey brings the Web content you need most to your mobile phone by allowing you to easily send it to your device. You can quickly mark content that is important to you and have that content always available while using your mobile phone." In other words, with the Joey Server, it will be possible to use Firefox to send text clippings, pictures, videos, RSS content, and Live Bookmarks to a phone. The Joey Server transcodes and keeps all of the content up-to-date.
The Joey application for mobile devices isn't complete yet, so users must use their current mobile browser to access information on the Joey server. Joey is currently in the early stages of development, but can be tested with Firefox, by creating an account at the link below. "The goal is to investigate the mobile space using a desktop-centric model. Like many other Mozilla projects, there are no plans to productize Joey. We will work with the community to build a compelling and usable tool that people will enjoy using."
