Not so long time ago i mailed them and they replied Avi, Aug-16 20:12 (PDT): Hi Paper, Thank you for contacting us! Currently Tango only supports the Android and iOS operating systems but we hope to branch out to more platforms in the near future! Please make sure to follow us on our Twitter, Facebook or Blog for the latest news and updates. You can also go to the the Feature Requests section of our forums to share this idea so the community can vote on it! http://support.tango.me/forums/327482-feature-requests Regards -Avi | TangoMe, Inc http://support.tango.me/home Free video calls from your mobile now we probably should mail them a lot so that they support maemo5 ,though chances are kinda minimal .
