In addition to release of new iOS 4.2 Apple updated their software bundle iWork for iPad, which includes Pages, Keynote and Numbers. So, what is new in this version of iWork? The most significant changes include:
For all programs:
Wireless printing with AirPrint using iOS 4.2;
Support for iOS 4.2 multitasking;
Localized in Portuguese, Danish, Finnish, Korean, Norwegian, Polish, Swedish, and Traditional Chinese;
DevTeam hacker MuscleNerd tweeted that they after releasing redsn0w jailbreak for 4.2 the team can start working on iPhone unlock. Users can expect the unlock for the iPhone 3G and iPhone 3GS this week. The iPhone 4 unlock will take more time and no concrete info is available about that yet.
The ultrasn0w unlock will be released for iOS 4.1 firmware. So is you need unlock, do not update to iOS 4.2.1.
DevTeam worked hard for the last several hours and released jailbreak tool for iOS 4.2.1. It is redsn0w 0.9.6 b4.
As usual we remind all ultrasn0w unlockers please stay away from this official firmware. Wait for the ability to create custom 4.2.1 IPSWs that don’t update your baseband!
New redsn0w 0.9.6 b4 uses limera1n exploit and will successfully jailbreak all devices. The only problem is that it is a tethered jailbreak, which means you will have to plug it to a computer and rerun redsn0w on every reboot. This so called tethered or semi-tethered jailbreak. This condition applies to iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC model), iPod touch 3G and iPod touch 4G. Hackers are working hard to create untethered jailbreak for these devices. To use future untethered jailbreak you need to save SHSH keys for iOS 4.1 using TinyUmbrella utility or directly in Cydia.
Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC model) can be jailbroken-untethered right now using this latest version of RedSn0w.
Finally, Apple released their rumored iOS 4.2. Here is a list of the new features and improvements added in this firmware:
AirPlay for steaming audio and video content to the Apple’s set-top box Apple TV with access to Netflix streaming.
Find My iPhone service became free for the current generation iPad, iPhone, or iPod touch.
AirPrint: the feature allows to print over-the-air directly to certain HP printers. Perhaps, the company is interested in looking into third-party solutions.
Apple finally released iOS 4.2 for iPhone 3G/3GS/4, iPad, iPod Touch 2G/3G/4G and even Apple TV 2G. Lot's of new features, especially for iPad. Apple calls new firmware 4.2, however the version is actually 4.2.1. Here are the download links:
