If you have just bought an iPhone below are a few tips that might help you.
1. Compass App – if you swipe the screen to the left on the built in Compass app you will get to the Spirit Level. Handy if you are putting a shelf up on the wall.
2. Calendar App – Open the app. To get a list view of all your appointments, just tap the magnifying glass icon. To see the week view, rotate phone from portrait to landscape.
3. Managing Cellular Data Use – go to Settings, Mobile (Cellular if in the USA), and scroll down whereby you will see how much data each app is using. If you see any alarm bells you can turn off the particular app using data. At the bottom, you can tap on System Services to see what data the individual services are using.
4. In iMessage, if you want to see the timestamps when a message is received, just slide message to left to reveal the timestamp.
5. To search your iPhone. On home screen, just slide your finger down in middle of screen to reveal search box.
6. Safari – to swipe between different pages, just slide left or right.
