2nd time this month, all my calendar entries have been wiped out. What a pain in the ****. I have not changed theme's, using the stock vzw one. I have done a battery pull, still nothing. Do I really have to re-enter everything? Why is this happening??
Are you syncing with google, and if so, is it happening on both sides? This was happening to me, but only affected the phone. I just deleted my calendar with DM, and re-synced with Google. All was fine after that.
I had mine set for save forever. But everything except face book birthdays in my Tour and Outlook calendar disappeared. I just checked the options in my Tour, and for some reason it was changed to keep appointments for 60 days.
