Glympse has updated its apps for iPhone and Android to give users the option of automatically showing a dynamic, live map of their location to their Facebook friends. The new feature expands the service beyond its existing distribution channels of email, Twitter and text messages. Glympse's Facebook integration uses a Facebook Connect unified login to allow people to choose to share an embedded map as part of their news feeds on the site. Apart from the location, the real-time map can show the speed of travel and the estimated arrival time, if the user designates a destination. The user sets the amount of time the location-sharing lasts, up to four hours, and after it expires, friends can only see where the Glympse user was immediately before the time period was over. Apple approved the update to the free Glympse iPhone app on Thursday, and the Android app was made available in the Android Market around the same time.
