Ok, I'm new to this forum, but I haven't been able to find help elsewhere. I have a 2G iPod touch, 16gig, *not* jailbroken. I've been using it (and loving it) since last December with no issues to speak of. I frequently use the built-in calendar app as a PDA to keep track of my schedule and appointments. This morning, when I went in to the app to check the time of a previously entered appointment, my calendar had been cleared. No future appointments, no past appointments, nada. I'm using the native app, and it's not synced with anything. I entered everything manually in the device and I don't use any other calendar program. Thus far, I've tried exiting and reopening the app, rebooting the device, and syncing with my computer, to no avail. Has anyone else had this problem or know how to fix it, or should I just get to work re-entering everything?
