How All The Great New Stuff In iOS 4.2 Works

While iOS 4.2 didn't bring all it promised (ahem, AirPrint), here's a look at all the major new features, how they work, and how to enable the ones that don't.


There has been a whole bunch of trouble over AirPrint lately, with Apple pulling AirPrint support from Mac OS X 10.6.5. What the feature was supposed to do is allow you to print a document or photo from your iOS device to any shared printer on your home network. Without support in the desktop operating system, this is pretty hard to do. If you're on a Mac, however, you do have some options to get that support back. The easiest way is to just install the missing files. Here are instructions on how to do that, or you can use AirPrint Hacktivator to automate the process. If you don't feeling like modifying your system, want a GUI and some added functionality, check out Printopia and Fingerprint ($US10 and $US8, respectively). They enable AirPrint support on your Mac with a friendly interface.

If you're not a Mac user, you're not barred from printing from your iOS device. Here are some tips on printing from your iOS device without iOS 4.2 if you really want the feature but don't meet one or more of the numerous requirements to get it to work.


AirPlay is basically a repurposing of the previously existing AirTunes technology Apple's always included, letting you stream music from your iOS devices to an AirPort Express or AppleTV. The reason the name has now changed, however, is because you can stream not only your music but video as well to AirPlay-compatible devices. At the moment, the AppleTV is the only device to which you can push video and currently it does not work. With the iOS 4.2 update now available, the AppleTV update — bringing AirPlay support — is imminent and we should see fully functional streaming very soon.

Note: we'll update this section with a look at AirPlay and how it works once the update is available from Apple.

Find My iPhone/iPad/iPod touch — For Free!

While it would be especially nice if Apple would make MobileMe a free service for all, they've take the baby step of enabling one of its better features — Find My iPhone — for all iOS users. Even if you don't pay for MobileMe, you can now use Find My iPhone (or iPad or iPod touch) for free. If you're not familiar, the service basically does two things: it helps you locate a lost iOS device or lock down your data if your device is stolen. You still turn it on in MobileMe preferences, but now it just doesn't cost you anything. In the event you lose your iOS device, you can use one of your other iOS devices or the MobileMe web site to track it or lock it down.

iPad Multitasking

Multitasking is a feature we've had since iOS 4 on the iPhone and iPod touch, but it's generally agreed that it's been sorely missed on the iPad more than anywhere else. Multitasking on an Apple device isn't necessarily true multitasking, but it allows you to switch between open applications without returning to your home screen. Developers are also able to suspend their apps while in the background and allow certain operations, such as audio playback, to continue even after leaving the app. This is great for fans of Pandora radio or other music services, who want to listen in the background while answering email, browsing the web, or doing anything else on their iPad.

iPad Folders

Just like with multitasking, folders have come to the iPad in iOS 4.2. Now you can tap and hold down an app, drag it to another app, and create a folder on your iPad. It works about the same as it always has in iOS 4 on the iPhone and iPod touch, but the maximum app limit is 20. While not particularly new, this is a very welcome feature on the iPad if you have way too many apps and need a way to organise them.

Want all these new features? iOS 4.2 is out now. Plug in your iOS device, open iTunes and get ready to update.


    it will only truly be an update worth getting once it is jailbroken and the jailbroken apps are updated to work on the new os

    Airplay is great on the ipod touch (2nd gen) then I turned the microwave on. Then the neighbor ect. Failed. Oh well will have to go live in the country.

    I believe that Find My iPhone is not available free to iPhone 3G owners. You can still get Find My iPhone for a fee through itunes. Mind you losing it wouldn't be a bad option anyway ....

    My understanding is find my iPhone is not only not available for 3G owners but also 3GS. Only iphone 4 owners get the free deal (or have other ios 4.0 original products)

    My 3GS works with free mobileme service, i didnt havr to do any workaround / hacking.
