With the iPhone 4 launch only a few days away, Apple has released iOS 4.0 (aka iPhone OS 4.0) to the masses. Now that we have the latest iOS on our fancy Apple devices, we decided to highlight some of the great new features and give you a some tips on how to fully utilize the OS.
To help you get ready for iOS 4.0, we have an article to help you prepare.
Update iTunes

iOS 4.0 only works with the latest version of iTunes. If you haven't updated iTunes to 9.2, do so now. You can fire up Software Update to get the latest version.
Backup Your iPhone

Before you upgrade your iPhone it's always a good idea to back up all of your data. While the chances of a error occurring and forcing you to go full restore are slim, it's always a good idea to backup your stuff.
Plug your iPhone and in iTunes, right click on your iPhone in the left panel. Select backup your iPhone from the drop down menu.
Wiggle Room

Don't completely fill your iPhone, leave at least 500MB of room for apps to load and save documents. If you fill it to the rim with media, chances are, you're going to have a very slow running iPhone/iPod touch.
Check for Updates

Apple's iOS 4 implementation of multitasking involves developers updating their apps to take advantage of the feature. If an app isn't updated, it won't take full advantage of multitasking and will have to relaunch each time it's selected. So you should update your apps as soon as they are available.
Multitasking

The main feature of the iOS is the ability to multitask. that mans you can more than one application running. Want to listen to Pandora while checking your email? iOS 4.0 can do that. To see the applications running and to quickly switch between apps double tap on your iPhone's Home Button.
Just tap on your app of choice and the app will load. Magical!
iPod Controls

Prior to iOS 4.0 when you would double tap the home button you were presented with the iPod controls. now that multitasking has taken over the home button double tap feature, here is how to reach the iPod controls.
Double tap the home button, when the multitasking drawer pops up, slide to the left and wham, there are your iPod controls.

Bonus: You can control apps like Pandora from the iPod controls in the drawer.

If you're iPhone is locked, the double tap still brings up the iPod controls.
Quit an Application

Multitasking is great, but sometimes you want to quit a program. In order to quit an app you need to enter the multitasking drawer. Double tap the home button to bring up the drawer. Tap and hold on an app. The apps should begin jiggling with a red circle with a minus sign in the the top left hand corner. Tap on that red circle and it'll close that app.
Orientation Lock

Tired of your iPhone switching to landscape in your favorite apps? You can now lock the orientation of your iPhone so it stays in portrait mode. Double tap on the Home Button to bring up the multitask drawer, swipe to the left menu and to the left of the iPod controls, you'll see the orientation lock. Tap to lock in portrait mode.

You can see the orientation lock status in the menu bar.
Pick a Search Engine

Tired of Google? You can switch to Yahoo! or Bing for all your search needs. Navigate to Settings > Safari > Search Engine. Pick your search engine of choice and have a nice day.
Search The Web and Wikipedia from the Spotlight Screen

Instead of launching safari to search the Internet or Wikipedia, you can do it from mobile spotlight. Navigate to the search screen on your iPhone. Type in what you're looking for, and you'll be given the option to choose The Web or Wikipedia.
Mobile Safari will launch and navigate to Wikipedia or your search engine of choice.
