Sprint (NYSE: S) has launched NextMail Locator for its Nextel Direct Connect customers, which lets them push-to-send their location, date, time and voice observations to a dispatcher, call center or another field worker. The location can be the GPS coordinates, physical street address and an interactive map. Unlimited use is $19.99 on top of the customers’ monthly plan including Nextel Direct Connect, so it seems to be aimed squarely at business users, but it’s easy to see how popular this could be with people uploading to social network sites if it becomes more widely available, especially if video were added. At CTIA Sprint said that it plans to offer new features on the push-to-talk system such as the ability to push-to-send photos and other content, and this could be the first step in that. Release.
