LG Fantasy/Miracle now caught in a video, WP Tango on-board
And if this rumour is true then we do know that the Tango will not have any change in the user interface but only new features will be added to the Tango OS as we saw yesterday.
Moreover the thing that forces us to believe that the device is running Tango is the existence of the 512 MB RAM on the device. And as we saw yesterday, Tango goes on to work on device with RAM as less as 256 MB. From the video we come to know that the device is almost same as that of the LG Spectrum and the only difference is the OS, from Android to Windows Phone.
