When you exit an application, it's still running in the background. If an app snags, you can force quit it without having to reset the iPhone. To force quit an application:
When you have a lot of Home screens, flipping to get to the first screen where most of us keep our most important apps can be tedious. Just press the Home button in an home screen and you're taken back to the first screen. Press it again and it calls up Spotlight to search your iPhone.
The iPhone Home screen is an electronic version of on of those slider puzzles. Move one icon and all go out of place.
The simple solution is to drag one icon to the right off the screen you want to add an icon too and place it on the last screen . This leaves a blank space as well as doesn't destroy all your other screens. Then drag the new icon in.
If flicking is just not your style you can tap your way through the Home screens. Just tap the leftmost or rightmost page marker dots at the bottom of the screen.
Apps for your iPhone can be huge. Edge and 3G have a download limit of 10 megs, which can take a while. If you need to pause the download to do something else at a faster speed:
Any Issue For just about any issue, restart your iPhone by holding both the Home and Sleep button (top right) together for about 7 seconds. Ignore the prompt. The Apple logo will appear letting you know your iPhone has restarted. Your data is safe. This is equivalent to restarting your desktop computer. If this doesn't work, try restoring. After you have connected your iPhone to your desktop, wait for the sync to finish. Click on the Sync button. Let it finish again. Click on the Restore button.
App Frozen Hold the Home button for about 6 seconds. This force-quits the app.
General Slugishness Like OSX, your iPhone can run many apps at once. For that matter, it's running all the apps you've started up since your last reset. You can exit apps you're not using by holding down the Home button while in that app. This will improve both speed and battery life. To turn off all apps at once, hold the Home and the Sleep button on the top right of your iPhone for about 10 seconds.
Web clips allow you to bookmark sites with an icon on your Home screen. This is very useful for those who use their iPhone for a dozen sites they regularly visit, since 16 will fit on their own page of your Home Screen. While this in itself is cool, the best function of these is that you can zoom in on a portion of a page. When you launch your Web clip from the Home screen it's pre-zoomed so you don't have to resize the page to read it. This trick works extremely well with Apple's discussion sites. If you zoom in on the top of the list of posts, they're legible without having to manually zoom or tap each time you go to the page. When you page back to this page, they remain zoomed in.
The main purpose of the Home button is to take you back to the Home screen with a quick press. But there are some secrets that make it very useful:
Just tap and hold any icon to get it vibrating. Drag it off the right side of the screen. This creates a second page. When done press the Home button to lock the icons. To get to the second page on the Home screen, swipe right. You can add up to nine home screen pages. Pages left blank will disappear when you lock down the icons.
You can reposition the icons on your Home screen. Just tap and hold any icon. When it starts vibrating, drag it any where you like. You can also drag the Phone, Mail, Safari and iPod icons onto the Home screen and replace them with apps you use more frequently. When done press the Home button to lock the icons.
