Will powering down remove all that is in RAM? To do this am I right to do as follows and how often should this be done? Powering down: Hold down the on/off switch until the power off slide switch comes on and then slide the switch to the off position. Powering back up: Hold the on/off switch and the home button down until the apple icon comes on. Than what do I do to get it started again? Will powering down erase my calendar entries and my notes that I have created?
