Push-to-Talk now available on Verizon Wireless Casio G'Zone Commando after update

Thanks to a new software update (C771M100) from Verizon and Casio, the Verizon Wireless Casio G'Zone Commando will now have Push-to-Talk capabilities. And better yet, that comes at no cost to the owners of the rugged handset. To enable the feature, you need to check with Verizon to make sure that the PTT feature code has been added to your device. Once that is accomplished, open the Push-to-Talk app and enable the feature by selecting “OK” and the side key on the Commando will automatically change to Push-to-Talk ready

But this firmware update is more than just adding one feature! Other changes include an improvement in security with the latest Google Security Patch, an update in Google Mobile Services to Gingerbread R8, a new video application to replace the VCAST Video app, addition of signatures on text and multimedia messaging, the ability to enter your PIN/Password in Lotus Traveler without error, the screen now locks when a call is ended via Bluetooth headset to prevent unwanted pocket dial, and finally the LED flash for missed call or text has been added back.
