Agree..If you do a factory reset (really a poor name for reasons explained below) you WILL erase your data!
Why is factory reset not a good term? It doesn't restore the device to the way it left the factory. It restores the device to the way it would have been if it had left the factory after the most recent update was applied. Factory reset does not remove OS updates.
