Few top hidden features of the IPhone...

How to take a screenshot of iPhone screen :


Ever wonder how software reviewers take pictures of the apps without screen glare? I’ll let you in on the secret: none. Just press the Home and Sleep buttons at the same time. You’ll hear a camera shutter (or, rather, the sound of a camera shutter), and your current screen is saved automatically in your camera roll. 

Press Home Once to Go to First Home Screen or Search:

But what happens if you only press Home once? If you’re at your first home screen, you’ll be taken to Search. If you’re in Search or at another home screen, you’ll be taken to your first home screen. No customization here.

Hold Home and Sleep to Reboot:

It doesn’t happen often, but it is possible that your iPhone will freeze up. When that happens, hold the Home and Sleep buttons until the screen goes black, and subsequently shows the Apple logo. This will probably take about eight seconds.

Hold Home for Five Seconds to Quit the Current App:

What happens to an app when you close it? It might look like it’s sucked down a black hole, but that’s certainly not the case. When you close an app, much of it remains in memory, so it can be opened again quickly.

To “force quit” an application in iPhone OS 3.0, press and hold the sleep/wake button until the slide to power off screen appears. Then proceed to press and hold the home button until the application quits (usually takes around six seconds).

Scroll Inside Frames and Text Areas With Two Fingers:

Occasionally you’ll find that you need to scroll within a frame or textarea within a page. Scroll with just one finger and you’ll move the whole page. To solve the problem, use two fingers. Now you can move around inside your little box.

Turn Your iPhone Horizontally for a Wider Keyboard :

All the built-in apps (and many third-party apps, too, now) offer a wider keyboard if you turn your iPhone sideways. If you practice, you can actually type with two thumbs on the wider keyboard.

Turn Your iPhone Horizontally for a Scientific Calculator :

But the keyboard isn’t the only thing that gets wider when you go horizontal. The completely unassuming built-in calculator unleashes it’s scientific power when tilted 90 degrees. It’s great for those moments of impromptu trig or exponents…!
