I read in a press release Feb 12, 2008
"Nextel Direct Connect is the world's largest and fastest push-to-talk service, with millions of users enjoying it today. As the leading provider of push-to-talk service, Sprint has the largest portfolio of Nextel Direct Connect devices, including the largest selection of rugged phones certified to Military Standard 810F for dust, shock, vibration, etc. Sprint also offers exclusive Public Safety push-to-talk applications such as Priority Connect, Emergency Group Connect and Priority Group Connect."
