yesterday I reset my phone to factory default, just because I wanted to clean things up a little and this seemed the easiest way. So I started with a backup through Kies... reset the phone... restored the backup.... NOTHING came back, not pictures, apps, nothing... my phone was still at factor default. so I began to start new.. I wanted my contacts and calendar to update first, so I set up my gmail account and set it to sync. Well, it wiped out my entire Google Calendar ONLINE.... the phone, containing nothing, overrode all of the online data and cleared it out going forward from yesterday. Why would it do this, and how do I prevent this from happening again. My calendar online is for our whole family, so there are 5 different calendars and every single one of them got wiped out.
