As we promised, here are some more tips to use your iPhone in a smooth way:

1. How to use other applications while attending a call:

This cool tip allows you to multi-task.  When you are on a call press the “Home” button. This minimizes the call screen. Thus you will be able to access the main screen of your iPhone where all the applications are available. If you want to return to the call screen, tap the green bar at the top of the screen.  

2. Save battery by turning off the Equilizer:

The equalizer eats up a lot of battery life by chewing up the CPU cycles. Go to “Settings” > “iPod” > EQ. Then change to “Off”.

3. Spell-check:

Hold your finger on the text till you see a magnifying glass appearing. Drag the cursor to the spot where you want to fix the spelling. That saves you from deleting every letter till you arrive at the error-spot.
