iPhone iOS 4.2, iPhone has gone stale by now

Those who want iOS 4.2 on their iPad and iPhone can get it right now by sniffing around the internet for the Golden Master

A moron could have uploaded a mislabeled beta version, or a miscreant may have uploaded something malicious. But the risk of installing an iOS 4.2 unofficial copy has climbed exponentially over the past week, as the continued lack of an official release means that something is wrong with or has changed regarding the iOS 4.2 version that’s already unofficially out there.

In other words, the iOS 4.2 golden master is stale by now, meaning that what you’re installing on your iPad or iPhone by grabbing the GM from a file-sharing cesspool is either defective or simply not the finalized version which will ultimately be released

We've already spent some time talking about what iOS 4.2 will do for the iPad (iPad 4.2). That's mostly because iOS 4.2 is mainly geared towards the iPad, adding many of the features that seemed to be missing after having some hands on with iOS4.
We are expecting 4.2 to land by tomorrow, but Apple hasn't made the date official yet.

AirPlay is one of the biggest features coming to iOS with the 4.2 update. It's the next step in the evolution of Apple's AirTunes. Users can stream content such as video and audio between their devices. Streaming can happen between the iPhone and Apple TV or even with third-party speakers equipped with the technology.

Control Ringer Volume
What's even more important, however, is that you may now adjust the volume levels of the ringer independently of the volume level of your iPhone's audio player or games.

Find in Safari
We are glad that Apple is finally bringing this feature to Mobile Safari. You can now search for a term within a page.

FaceTime Through SMS

New SMS Alert Sounds

AirPrint

Midi Out
Like the iPad, the iPhone now supports midi out. A user can create midi data, such as a drum loop or musical sequence and connect their iPhone to a midi device with a USB port to make it playback the sequence they've composed.
Improved Performance on iPhone 3G
iOS 4.2 may see some improvements on the iPhone 3G. iOS4 was very difficult to run on the handset and rendered it almost unusable for some owners. Apple launched 4.1 later, which featured some improvements but many users were still unhappy with the performance.

The added features will be a welcome addition to the operating system.
