So my first iphone bricked itself and I got it replaced, which is all fine and I restored my backup. But now when I sync, no calendar changes on my computer or my iphone are being mirrored with eachother. I've tried resetting sync history, deleting app sync data and rebooting, exporting all ical calendars then resetting sync data, re-importing, and still nothing. Ideas? 10.5.6, latest iphone firmware.
