Today I found the link to the manual of the ipad .
Features have changed but most is unchanged and gives you a better oversight wat is possible.
Some features have changed like the lock on the rotating screen.In some versions ago apple decided that this became the mute button. Now you have to press the home button twice.
And swipe to the end untill you see a grey arrow and a cirkel.
After you have done that a cirkel with a padlok will show up and your ipad will not turn your landscape versus letter model
Oh and the link is here for the ipad manual
