The Samsung Wave was one of the very first cell phones released with the Bada OS incorporated in it. Since then, Samsung has not released any other phones in the meantime, but they have launched a search for SDK developers in order to take this already amazing OS to a whole 'nother level. Developers wanting to download the OS can simply visit the Samsung website and sign up for free! Just think, YOU could be one of the developers that advances this OS and you would get all the recognition!
