Kyocera Echo

Don't worry, faithful Kyocera Echo owners, your two dual screens are not forgotten about. Sprint has just announced an OTA update that will bring some bug fixes and security enhancements your way. This update addresses the MMS audio issue where the audio would cut out after 8 seconds as well as makes changes to the roaming guard display. In addition they have activated the Commercial Mobile Alert System in this update and implemented some security fixes. If you have an Echo and have yet to receive the update, be sure to check manually for it.
