Although the Google Nexus One has been available since
June January 2010, and many new phone models have been released since then, the development community is still very active. This hack, made by XDA member Nushio, is another example of that: it allows you to answer and end calls with a simple click on the trackball. It also includes many other small but very useful features to make it a complete software add-on that – in our opinion – really increases user experience.
