Snap Screenshots

If your iPhone is up-to-date, you can capture an image of anything on-screen. Just hold the Sleep/Wake button for a moment while you press and release the Home button. Your screen will flash white, and the photo will be saved in your Camera Roll in the Photos application. 

Shuffle Up Your Icons

Move icons around to create a new order. Simply hold your finger down on one for about two seconds, until they all start to wiggle. You can drag them around to whatever location you’d like, replace the icons that are in the dock, or tap the X to uninstall an app. To stop the wiggling and lock things in place, just press the Home button.

Extra Home Screens To The Rescue

Once you start adding application and bookmarking your favorite sites onto the home screen, you’re going to run out of room on your main Home screen. So what’s the solution? Just add more!

Hold down your finger on an icon to put the icons into the shuffle/wiggle dance, and then drag one off to the right side of the screen. The phone will create a new empty screen, and you can fill it up with whatever you want. If you look at the bottom of the screen as well, you’ll see a few dots, depending on how many Home pages you’ve created, up to nine total. Whichever one is bright white represents the screen you’re currently on. Drag all the stock applications you never use off to your last screen, that way they won’t get in the way.

We Have Contacts

The Contacts application hides lots of secret fields to store much more information than names, addresses, and phone numbers. When entering information, tap the name of the field to pull up many new choices. For example, tap mobile to choose from many other phone lines. But if that’ snot enough, scroll further down, and press Add Custom Label. When creating a contact, you can even tap Add Field at the bottom to create an entry for birthdays, job titles, and more.

Double-Tap to Zoom

The iPhone screen doesn’t just respond to single taps. It likes double taps as well, and it can come in handy as a time-saver. If you’re using Safari, you can double-tap to zoom in on a block of text or a photo, and then double tap again to back out to the full page-view. Viewing a photo? Double tap will zoom you in to the center of the photo, and you can double top again to zoom back out. Plus, in the Maps application, double-tapping will zoom and center the view towards wherever you’re tapping, however if you tap with two fingers, it will zoom you back out. It’s much easier than pinching.
