As with i OS 7 and 8, pulling down on any homescreen will show Spotlight.
In 2005, when Steve Jobs began planning the i Phone, he had a choice to either "shrink the Mac, which would be an epic feat of engineering, or enlarge the i Pod".
This feature is only available on third-generation devices—i Phone 3GS, third-generation i Pod touch (i OS 4.0 or newer), all i Pad models (since i OS 3.2)—or newer.
Researchers found that users organize icons on their homescreens based on usage-frequency and relatedness of the applications, as well as for reasons of usability and aesthetics. Apple switched to Helvetica Neue exclusively for the i Phone 4 and its Retina Display, and retained Helvetica as the system font for older i Phone devices on i OS 4.
When a passcode is set and a user switches on the device, the passcode must be entered at the Lock Screen before access to the Home screen is granted.
In i Phone OS 3, Spotlight was introduced, allowing users to search media, apps, emails, contacts, messages, reminders, calendar events, and similar content.
Originally, i Pod Touch users had to pay for system software updates.
