Since iOs 4, you can disable your iPhone’s auto rotation feature without additional software. This can be obvious for a lot of iPhone users but I keep telling people who didn’t know. The other day, queuing in the airport I heard two guys saying “I can’t understand why Apple doesn’t do the same thing for the iPhone that did for the iPad [to prevent the landscape mode when flipping the iPhone]” We need a short post about this, I said to myself.

To prevent the screen from flipping automatically on your iPhone do the following:

• Tap the home button twice
• The multitask bar will appear
• Swipe your finger to the right the furthest until you see the iPod controls

• Tap on the lock image

• Done, your iPhone has auto rotation locked. Check that in your status bar you’ve got an icon showing that.

To restore auto rotation follow the same steps the other way around.
