For all you cheapskates out there with Sony Ericsson mobile phones, Sony has just announced the release (dated 11 days ago) of Bluetooth Remote Control 1.0. The application (3 MB download, release notes) is intended to provide functionality very similar to the popular Salling Clicker.
Right now, only the Sony Ericsson K700-, S700-, V800-, and Z800-series phones are supported. More ambitious readers may wish to grab Sony Ericsson’s Bluetooth HID developer guidelines (500K PDF) and see what sort of support on older phones is possible. If you get anything other than the four supported models working, please post details in the comments.
