My phone is synced with my google calendar, gmail and contacts and it all works perfectly, going from those apps to my phone. However, when I add an appointment on my phone while I am out it will delete the appointment from the phone the next time it syncs, which it does automatically. So what I am wondering is if there is any way to make it do a 2 way sync or at the very least not delete appointments from the phone. Also I have an HTC Ozone with windows mobile 6.5.
