It was only two days ago that the HTC EVO 3D received its first update to address an issue with certain calendar events, and while that update may have fixed those issues it seemed to cause more. Upon updating early adopters found that their lockscreen was missing the dialer shortcut and any attempts to add it back failed. In the same fashion as the first update, the new update is being pushed out rather quickly and EVO 3D should be receiving their notifications for the OTA soon. Be sure to let us know how it goes.
