Are your appointment still on your account server, if you use gmail calendar, are you able to see your appointments on a browser? If yes then setup again your email accounts and calendars.
I was not aware that Apple or any of the carriers had a 4 G iPhone. That said, I use Google for my calendar and contacts. Both are kept on the Google servers/cloud and unless I delete one it remains. I suggest that you try to reinstall your calendar settings.
This happened to me as well. Go to setting and click on mail,contacts,calendars, scroll all the way down to the bottom and click on sync. then check all reminders. This should work.
