News tagged ‘iOS 4.1’

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.

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.

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:

DevTeam recently released new version of redsn0w to jailbreak iOS 4.1. New RedSn0w 0.9.6 b1 supports iOS 4.0 and iOS 4.1 running on iPhone 3G or iPod touch 2G.

There is only Mac OS X x86 version, that you can download 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.

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).

If you still had any doubt that the new Apple TV runs iOS, this will surely make you a believer. Apple has already placed iOS 4.1 for the 2nd-gen Apple TV on their servers and yeah… get downloading!

The iPhone 4 launched this weekend in Qatar and the United Arab Emirates, but buyers wound up with a surprise -- their handset's front-facing cameras couldn't do FaceTime. Carriers are blaming Apple for the missing feature, and spokespersons from both Etisalat and Vodafone say they're speaking to Cupertino about reinstating FaceTime post-haste; It was reportedly advertised on Middle Eastern versions of Apple's iPhone website until around September 20th, when all references to FaceTime were removed. TUAW reports that some UAE denizens have actually tested FaceTime on phones bought abroad and found it working just fine, but that the functionality disappears after installing the local version of the iOS 4.1 update.

Apple's iOS 4.1 update brought HDR photography to the iPhone 4 but left out the iPhone 3GS. Here are two ways to add HDR photography to your unsupported device.

Are you looking forward to add a very popular HDR feature to your old iPhone? Do not worry! If you have a jailbroken (or ready to jailbreak) iPhone 3GS or 3G that runs on iOS 4.1, you can enable HDR photos. Here is a quick tutorial:

The addition of high dynamic range photos to the iPhone 4 via the iOS 4.1 software update may have come from the purchase of Imsense Ltd., a company that creates software to improve the quality of digital photos.

The company developed technology it dubbed "eye-fidelity," which allows for dynamic range correction in both standard and HDR photos. This is accomplished by recovering details lost in underexposed and overexposed pictures. The resulting effect, in some cases, results in superior pictures when taken in daylight or a bright setting.

Only a few days passed since Dev Team has confirmed that Comex will try to jailbreak iOS 4.1, using other exploit. However, according to the response received on Twitter, it became known that Comex may not take part in the new iOS 4.x jailbreak.

Comex replied to the message on Twitter in such a way: "ariif, the next jailbreak might not be from me ".

Of course, it does not mean that Comex leaves the scene and would not take part in jailbreaking as Geohot, most likely it is only this version he isn’t planning to jailbreak. Nevertheless the smile in his reply certainly means something good...

According to the latest tweets from different hackers (MuscleNerd, pod2g and others) the exploit for iOS 4.1 has been already discovered:

Works on 4.1 (!) iBSS iv=c2c5416472e5a0d6f0a25a123d5a2b1c key=1fbc7dcafaec21a150a51eb0eb99367550e24a077b128831b28c065e61f894a0

I just successfully updated to 4.1 without a baseband update. PLEASE wait for 4.1.0 TinyUmbrella!!!

Crazy timing that @pod2g got latest exploit just as 4.1 went public (lots of work left...keep away from 4.1 for now!)

congrats to @pod2g for the latest exploit and also @p0sixninja who have been trying for months.

This means that the jailbreak and unlock for iPhone and iPod Touch is possible. However please be patient and wait for the utilities.

Following the release of iOS 4.1 Apple updated the iOS SDK today to build 10M2309. If you are a developer you can download it here.
