Choose General > Home Button to set preferences for double-clicking the Home
button. You can set iPhone so that double-clicking the Home button goes to the
Home screen, Phone Favorites, or iPod.
Set whether double-clicking the Home button shows iPod controls: Turn on Show
iPod Controls to display iPod controls when you’re playing music and double-click the
Home button. This feature works even when your display is turned off or your iPhone
is locked.
Date and Time
These settings apply to the time shown in the status bar at the top of the screen, and
in world clocks and calendars.
Set whether iPhone shows 24-hour time or 12-hour time: Choose General > Date &
Time and turn 24-Hour Time on or off. (Not available in all countries.)
Set whether iPhone updates the date and time automatically: Choose General >
Date & Time and turn Set Automatically on or off.
If iPhone is set to update the time automatically, it gets the correct time over the
cellular network, and updates it for the time zone you’re in.
Some carriers don’t support network time in all locations. If you’re traveling, iPhone
may not be able to automatically set the local time.
