Apple recently released the long-awaited firmware 4.2 for iPad, iPod Touch (4th generation) and iPhone 4/3GS. Under the two golden master versions you can use more than 100 new features. On the iPad you can now create Folders, use Multitasking, unified inbox in Mail app, Game Center and functions AirPlay® and Airprinting.
Due to the lower RAM capacity than it has iPhone 4, the source code has been optimized, making applications faster and taking up less memory space. AirPlay® adds the ability to stream video, music and photos wirelessly from your iPad, iPhone or iPod Touch directly to your Apple TV. Function AirPrint, on the other hand, adds the ability to wirelessly print documents from iOS device. Also new is text search in Safari or the ability to change the font in the Notes application. Last but not least, let's mention 17 new SMS notification tones and the ability to assign a different SMS tone to each contact.
Together with today's release iOS 4.2 is another surprise for users, as Apple from today on offers Find my iPhone free. This great feature is no longer tied to your MobileMe account. You can download the app from App Store under the title Find my iPhone and its main attraction is the ability to locate lost iOS device on the map, send a message or sound alert to this device and, if necessary, block access to the data on the phone or erase it outright. However, please note that this application will only be available for iPad, iPhone 4 and iPod Touch fourth generation!

To start the service Find My iPhone, use the following instruction.

I expected an update to come out at the same time Apple TV 2G to work on it AirPlay also for the video as it was presented. I have it on my iPad and iPhone 3GS iOS 4.2.1GM and there VideoAirPlay doesn't work. If you download the official OS4.2 and have a new ATV, please let me know if it works. AirPlay sound and picture. Thanks!!! I'm still convinced that ATV needs to be updated - even LP files from iTunes don't work on it Store, even though they are pedaling on ATV 1G.
will it be for 3G?
So the new SMS tones are nowhere to be found!
So I was not wrong, UPDATE on Apple TV came out at 19:50 PM our time.

I confirm that after updating ATV from iPad with iOS4.2.1GM works AirPlay for both video and AUDIO!
to ZEMi: They are directly in the ringtone settings.
AirPlay works on ATV2G and from iPhone 3GS!

Thanks
Great...I'm updating from 4.2 GM and downloaded the new itunes from apple.com …I got an update and it won't install on my iPhone …so it doesn't work for me iphone…write it to me:”…cannot be restored ...server could not be contacted.." you don't know what to do with that?
AirPlay videos, even H.264 720p movies, from your iPad over WiFi to TimeCapsule without a single stutter or problem with real-time streaming.
Does that one work? AirPlay on iPod 2nd gen. ????if yes then how?
I want to ask what's wrong with that. iOS baseband?
will it be unlocked?
I'm downloading like crazy, it's slow and after two hours it gives me a connection error a minute before the end... :)
I guess I'd better wait until tomorrow, until things calm down a bit
Bernice: iOS 4.2.1 will of course be and will run on the iPhone 3G
Roman: Try to hold on a moment, now they have Appwow, terrible rush of updates
Jiřík: I'm not entirely sure, but I think so. airplay on iPod Touch 2nd generation will work :) http://www.youtube.com/watch?v=ciI82ZzurX8
vaasd: I don't know the baseband off the top of my head right now, but the Dev-Team should release the unlock in a few days :) of course you can LsA expect instructions as well.
Míla: Thanks for the information :)
Blah: I don't think much has changed since the last GM version :)
Thomas: try it iOS download from this page :) hope it works for you ;) http://www.coveringweb.com/2010/11/ios-421-is-live-available-to-download.html
V AppStore UPDATE programs are available for download KeynoteSat Numbers (surprisingly not Pages) for iPad. These versions already include support AirPrint!
U KeynoteIt is speculated that it will be able to play presentations via ATV2G in the future AirPlay. Today's UPDATE Keynotebut he can't do it yet.
Works from the Photos app AirPlay also – slideshow with music and scroll through photos manually.
I have an iPhone 4 and after the update I still don't have it there AirPlay. And to top it all off, my phone won't find the printer via Wi-Fi :-( Do you know how this is possible?
Just throw it iPhone into dfu mode and I already have 4.2.1

??? Maybe I'm blind or I just don't have it there!!
ZEmi, here's a link where they discuss it: http://forums.macrumors.com/showthread.php?t=1052925
Unfortunately, it looks like the new sms tones are only for IP 4G :(
ZEMi: I have 3g and also only original sounds :(
it's great that the iP4 has tones and the 3GS doesn't:D it's really hard on the hardware that the 3GS doesn't have it anymore!!
AirPlay only works on AppleTV or something else? I don't have the blue icon on my iPod at all AirPlay
and where can I get that one airCan I get port express?
I notice acceleration on 3G. But also when draining the battery. :(
Good day, I would like to ask if anyone knows how to use the search function across the website in Safari? From this update it should be possible. Thank you
You don't know how it is with jailbreak and unlock?
Yes, I already found it, but thank you
And how is the baseband there, does unlock work?
After updating to a new one iOS My Wifi stopped working on 4.2. The phone searches but doesn't find any network. Everything was OK on version 4.1. I have Iphone 3GS. Please give me some advice. Thanks
