Engadget published a howto video of LimeRa1n - iOS 4.0-4.1 jailbreak utility for iPhone, iPod Touch and iPad:

Famous hacker Geohot is back and today he released the latest iOS 4.1 jailbreak. It is called LimeRa1n and supports iPhone 3GS, iPod Touch 3G, iPad, iPhone 4, iPod Touch 4G with iOS firmwares 4.0-4.1 and beyond. It can also hacktivate your device, so there is no need in phone SIM-cards and other tricks.

This software is still in beta and was updated 3 times in last several hours. So use with caution.

There is Windows version only for now. Geohot plans to release LimeRa1n for Mac and Linux soon. You can Download it here.

Some users report that they have jailbroken their iOS 3.2.2 iPads successfully with limera1n, while others report that they tried, but failed.

Do not forget to backup.

For many users of iPhone 3GS and iPhone 4 with iOS 4.0.2 now there is a hope to perform jailbreak using LimeRa1n and unlock using ultrasn0w. We recommend NOT to do it if you have not saved your SHSH keys. You can try, but if something goes wrong without SHSH keys you'll have to restore to iOS 4.1, and there is no unlock for iOS 4.1 (possibly forever). Just wait for PwnageTool utility.

DevTeam reported that Limera1n uses a different exploit than SHAtter, so they will not release SHAtter utility, they don't want let Apple fix both security holes. However they plan to release PwnageTool using the same exploit.

You can find our LimeRa1n tutorials tutorials:

• iPhone 3GS, iPhone 4, iPod Touch 3G, iPod Touch 4G (Mac)
• iPad (Mac)

• iPhone 3GS, iPhone 4, iPod Touch 3G, iPod Touch 4G (Windows)
• iPad (Windows)

RedSn0w 0.9.6 b1 for Mac OS X was released a while ago. Today DevTeam created a version for Windows users. RedSn0w 0.9.6 b1 can jailbreak iOS 4.1 and iOS 4.1 running on iPhone 3G or iPod touch 2G.

You can download it here.

Redsn0w is easy to use:

1. Download firmware here.
2. Launch redsn0w 0.9.6 b1
3. Select your stock 4.1 or 4.0 ipsw (you’ve already used this to update your device to 4.1 or 4.0)
4. Select “Install Cydia” and any of the other options shown above, then click “Next”. Use DFU mode to install the jailbreak.

This is still beta, so there might be some problems:

Any Windows users seeing “Waiting for reboot” for too long (more than 20 seconds or so), please try “shaking” the JB process by unplugging then replugging your USB cable (while letting redsn0w continue to run). Also, try using a USB port “closer” to your computer (as opposed to on your monitor or behind another hub).

As usual DevTeam reminds us:

IF YOU USE THE ULTRASN0W UNLOCK, PLEASE WAIT FOR PWNAGETOOL TO SUPPORT 4.1. DO NOT USE REDSN0W

That’s because to use redsn0w at 4.1, you need to already have updated to official 4.1 from Apple. If you do that, you lose the ultrasn0w unlock (possibly forever).

Chronic Dev-Team member Joshua Hill has just confirmed that the new Greenpois0n jailbreak, which will allow you to jailbreak Apple’s latest iOS 4.1 software, is expected to be released this Sunday. To make the event more special, Dev-Team has decided to launch the tool at 10 past 10 AM on October 10th 2010. They will be releasing multiple tools, some of which will help you update to 4.1 without losing the possibility of unlocking your baseband for other carriers.

Apple dropped support for AirPrint in iOS 4.2 on the iPod touch 2G. When Apple just released AirPrint on September 15th, the second-generation iPod touch was listed as a compatible device for the service, but only two days later the company dropped support and modified the press release to note support for only the third- and fourth-generation iPod touch.

Apple updated its MobileMe Gallery application for the iOS platform. The application was realized in January this year.  Current update brings iPad computability and full support for the higher-resolution Retina displays of the iPhone 4 and fourth-generation iPod touch. In June Apple already added the ability for the iPhone 4 to download higher-resolution photos, but this update extends Retina display optimization to the entire application. The update also brings support for multi-tasking and the ability for iPhone and iPad users to view friends' galleries without the need for a MobileMe subscription.

Developers who have already installed iOS 4.2 beta 2 on the iPad report that the device's performance increased compared to first beta and to 3.x. iPadevice made some testing, here's what they've got (the smaller is better):

9to5mac reports that there is a new feature found in recently released iOS 4.2 beta2.

YouTube allows video uploaders to choose whether their video is public, private, or unlisted. Public video is available for everyone to see, private is for uploader and friends only and unlisted makes the video only viewable from a direct link or embed.

This feature has just arrived in iOS 4.2 beta 2:

The iPad got a new animation for quick-app-switching/multitasking in recently released iOS 4.2 beta 2. We already have a video. Here’s how it looks now:

The developer Dustin Howett has managed to port AppleTV software called Lowtide to an iPod Touch and run it under iOS 4.1. You can see it on a demo video below. It's really amazing how compatible these new systems are.

Here are comments from the developer:

This is FrontRow, as shipped with the AppleTV 2 (ARM), running on the iPod touch, 4th Generation. It doesn't respond well to touch input, nor does it like the resolution of the device.

Apple today released the new beta of iOS 4.2 firmware (iOS 4.2 beta 2), the software development kit (SDK) and Xcode 3.2.5. This is available for developers only.

The update includes:

• iPad multitasking gets new animation
• New YouTube video uploading options
• New Game Center compatibility indicators on mobile iOS App Store

iPhone developer, chpwn has just provided a very interesting link via Twitter, a download for the Apple TV iOS 4.1 firmware.

You can download Apple TV iOS 4.1 here. There is not much use of it currently, however it does give hackers a possibility to analyze it.

The new exploit is called SHAtter. It was developed by hacker pod2g a few months after hacker p0sixninja from the Chronic Dev Team discovered the crash. The same exploit can be used to jailbreak iPhone 4 and iPad with new firmwares. So iOS 4.1 and maybe even iOS 4.2 is not a problem any more. Soon we will see the utilities from DevTeam to perform the jailbreak.

The DevTeam published a video if a jailbroken iPod Touch 4G. Take a look:
