Symptom
Calendar data is lost or duplicated when you sync your phone with iSync 1.2.1.
You have previously used Terminal to allow iSync 1.1 to sync calendar data with an unsupported mobile phone.
Solution
There are two solutions. Review both and use the best for your situation.
If iSync 1.2.1 or later is not yet installed
