An open source app that synchronizes Google Calendar with your phone’s built in calendar.  It’s not perfect but it’s the only app of any kind that I know of which synchronizes the calendar on Motorola iDEN phones with anything. The issues I’ve found with it are:

It asks permission to access user data a half a dozen times ever sync with annoying beep each time.  You can eliminate the beeping by switching to a profile that has Volume > Data set to 0.

It only syncs event name, date and time.  It does not sync location, description or alarm (alarm is always off).

Using the  default settings event times will be off by several hours.  To fix this go into Options > Time zone and un-check “Use GCal time zone” (see image).
