Finally, the iPad, iPod touch and iPhone are on a level iOS field. Multitasking, folders, printing, all the big ticket items are there. But what about some of the smaller tweaks to the OS?
We jumped right in to the latest iOS update and have emerged with a list of tips, tricks and features that'll help you get the most out of your iPhone, iPod touch and iPad.
UPDATES!

You need to update iTunes and OS X to update your iPhone, iPod or iPad to iOS 4.2. If you haven't already updated, go ahead, update. We'll wait.
Backup Your iPhone, iPod or iPad
Before you upgrade your device it's always a good idea to back up all of your data. This is especially important when you haven't synced your device in a while. 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 device into iTunes, right click on your device in the left panel. Select Back Up from the drop down menu. It might take a while, but it's worth it if things going horribly wrong.
Multi-tasking for iPad

Run more than one app at a time with the multitasking feature. To see which applications are running and to quickly switch between them double tap on your iPhone's Home Button.
Quit Apps
Apple may say that you shouldn't have to mess with quiting apps on your iOS device. That doesn't mean that you don't have the ability to actually quit apps.

Double-tap the home button to see the app drawer. Tap and hold on one of the ope apps and they'll get the jigglies. Tap on the red circle in the other left hand corner of the offending app and it'll quit.
Folders for iPad
The iPad now joins the iPhone and iPod touch with folder support.

Tap and hold on an app to start your apps jiggling. Drag two apps together to create a folder. Your iPhone will create a folder and automatically give the folder a name based on the category of the apps. You can can change the folder name to something more appropriate. You can then drag up to 20 apps into your folder.
To remove an app from a folder. Open the folder, tap and hold on the app you want to remove. Drag it out of the folder.
Find My iPhone

If you've lost an iPhone and you haven't signed up for MobileMe, you know the pain and misery of trying to track it down without Find My iPhone. with iOS 4.2 you get free, that's right free, Find My iPhone. There is a catch, you need to set it up with an iPhone 4, iPad, or 4th generation iPod touch. Once that's done, you can find all your iOS devices.
Print
Before you fire up the email client and start printing all those emails from Steve Jobs, we got some bad news for you.

As of press time, only AirPrint-compatible printers will work with your iOS 4.2 device. The shared printing feature Apple showed off before, it's not in this release.

HP ePrint enabled printers are ready for AirPrint. So if you're in the market for a printer and you really want AirPrint, there ya go.

Hopefully, we'll see shared printers in AirPrint soon.
What can print and what can't
While Apple has asked app developers to add printing support to their apps, Apple hasn't flipped the printing switch on some of their own apps.
Here is a list of Apple apps that support and don't support printing. Some of the apps that don't support printing are just confusing.
You can print from Photos, Email, and Safari.
You can't print from Calendar, Notes, Messages, Maps, and Contacts.
Open in…

If you navigate to a PDF or other document format, like ASHX, in Safari you can tap on the page and it'll give you the option to Open in…

Tap it and it gives you a list of apps that can handle the file type.
App tray
Double tap to show the app tray.
Swipe to the left once and you'll see:

Speaking of Orientation Lock

You've probably seen the hubbub abut the orientation lock button on the iPad turning into a mute button. Well it's true. To lock the orientation of your iPad you have to double tap the home button to enter the app tray and swipe left.
