I was entering in a bunch of calendar events for next year through the Google calendar interface on my computer. Everything synced to the phone except items entered for Sept - December 2011. They are present in Google Calendar, but not on my phone. If I enter an event on my phone in one of those months, it syncs and shows up in Google Calendar, but nothing entered in Google calendar in those months shows up on my phone. I've tried clearing out Calendar Data and Calendar Storage Data but that didn't help. Anyone else see this?
