After being in closed beta for six weeks, Vringo Studio is now live. This is a new Web application that "lets anyone become a video ringtone producer". Essentially, you take video clips from Vringo’s 4,000-strong clip library or upload your own, customize it and the application then creates a personalised video ringtone, a 'Vringos'. What do you think of this service or the idea of video ringtones?
