I just got off the phone with samsung and at&t and they said that google doesn't support the syncing of the phone calendar to your Google calendar. My wife just lost all her appointments. Has anyone else come across this? I can add a task or appointment on the Google calendar and it'll show on the phone's calendar but if I add an appointment on the phone's calendar it will not sync to Google. Now I have to find a calendar that will sync with my google calendar.
