Even more iPhone tips and tricks

-Hi, I'm Sharon Vaknin, and I'm here to show you how to make the most of your iPhone with some useful shortcuts and tricks. Long time and recent parents of iPhones, listen up. I guarantee you did not know at least one of these useful tips. So, you know your iPhone is equipped with a very useful alarm, stop watch, and timer. What you may not know is that you can use that timer to put your iPod in sleep mode. Open the clock app, "select timer," and adjust it to the duration you'd like the music to play before it shuts off. Then tap "when timer ends." Scroll to the top and select "sleep iPod." Click "set," start the timer, and play your music. Now, here's a simple tip for when you may be too busy to answer a phone call. You know that clicking "ignore" when there's an incoming call will send your caller to voice mail. Well, a faster and equally reliable method is to click the sleep button while your phone is ringing. Your caller will be sent to voice mail and your phone will stop ringing. Here's one of my favorite tricks. There are times when you may want to look up a phone number, find directions, or play Angry Birds during a phone call. Well, you can actually do it all because AT&T allows us to use voice and data at the same time. During a phone call, just click the home button and you're free to use your phone as usual. Just tap the green bar at the top to return to your call. A lot of you iPhone users are aware that you can zoom in on an e-mail, photo, or web page by double-tapping with one finger. Well, this function isn't always available especially within apps. So, go to settings, general, and select "accessibility." Click "zoom" and slide it to "on." Now, you can zoom in anywhere by double-tapping with three fingers. Unlike every phone, the iPhone is equipped with a calculator for doing the simple calculations like adding and subtracting. But those of you who need more advanced functions like finding the square root of a number or using exponents can turn to the built-in scientific calculator. Just rotate your phone to landscape mode and, voila! Well, there you have it: a few tips to help you use your iPhone to its full potential. For CNET.com, I'm Sharon Vaknin. See you next time.
