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 cannot use JailBreakMe method to jailbreak and unlock iOS 4.0.2 on iPhone 3G. However you can still jailbreak and unlock iPhone 3G using redsn0w. Here are the instructions:

• Download the latest RedSn0w 0.9.5-b5 in our utilities page here.
• Download firmware images for iOS 4.0 here.
• Run RedSn0w and point it at the 4.0 IPSW. (Yes – point it at the 4.0 IPSW even though you’re at 4.0.2). This will also hacktivate your iPhone3G at 4.0.1 if you haven’t already been activated by iTunes.
• If you need a carrier unlock – install ultrasn0w in Cydia (add repository http://repo666.ultrasn0w.com). For T-Mobile in the USA remember to turn off 3G mode in Settings→General→Network.

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.

Having problems activating your iPhone? Don’t have original SIM-card? Cannot get passed emergency unlock screen? We have a solution:

If you have iPhone 3G, just use redsn0w to jailbreak and hactivate. If you have iPhone 3GS or iPhone 4 follow these instructions:

If you are already Jailbroken:

So you have an iPhone with iOS 4.0, but don’t have the original SIM and stuck on the Emergency Call Screen:

1. Download ifunbox software (download link)
2. Run ifunbox software and sync with phone
3. Go to /private/var/root/Library/, delete original lockdown folder and put this lockdown folder after you extract it from the zip file
4. Restart phone

If you are not jailbroken

MuscleNerd tweeted today that the recent redsn0w utility is able to jailbreak the iOS 4.1 beta2 on iPhone 3G and iPod Touch 2G. This is useful for developers only, however good news for everyone.

Here’s some info from the DevTeam wiki page:

MuscleNerd, hacker from DevTeam, commented via twitter on recent rumors that universal jailbreak (all iPhones and all firmwares, including iPhone 4 and iOS 4.0.1) will be released today. The basic answer is no, there will be no jailbreak today.

Not to make it a daily thing, but since somehow people thought it would be today: the new JB+unlock won’t be out today

(there are issues with important apps like Facetime that need to be figured out…no sense releasing a half-broken JB)

Jay Freeman, better known as Saurik, the creator of Cydia, was interviewed by the home radio Make It Work. He speaks about the history and the future of the iPhone jailbreak.

Saurik describes the origins of Jailbreak and Unlock for the very first model of the iPhone. Jay explains that initially there were two important things to do with the iPhone 2G -- to use other carrier than AT&T and to install any application.

He continues discussing the main applications from Cydia. Cycorder was the first to allow video recording, and Winterboard was the only one that allowed users to change the graphical interface of the iPhone. He also speaks about Comex, the hacker who is currently working with the Dev Team for releasing and Unlock for the iPhone 4. According to Saurik the tool is still not ready to be released to the public due to severe bugs in the code. Here the second part:

There is no official jailbreak utility for iOS 4.0.1. However you can still jailbreak and unlock iPhone 3G. Just do the following:

• Download the latest RedSn0w 0.9.5-b5 in our utilities page here.
• Download firmware images for iOS 4.0 here.
• Run RedSn0w and point it at the 4.0 IPSW. (Yes – point it at the 4.0 IPSW even though you’re at 4.0.1). This will also hacktivate your iPhone3G at 4.0.1 if you haven’t already been activated by iTunes.
• Install ultrasn0w in Cydia (add repository http://repo666.ultrasn0w.com) if you need a carrier unlock (and in the USA, remember to turn off 3G mode in Settings→General→Network).

Here’s what hackers tweeted about new Apple firmwares 4.0.1 for iPhones and 3.1.2 for iPad:

DevTeam:

As with *any* new FW, jailbreakers + unlockers must avoid this upcoming 4.1 update until our tools are updated

3GS, ipt3G, iPhone4 users (regardless of current FW or JB status) should backup 4..0 SHSH blobs http://is.gd/dskh9 soon

MuscleNerd:

Obviously avoid today’s 4.0.1 update until JB tools are updated. Luckily, no baseband change so ultrasn0w lives on 🙂

each FW version has unique blobs. But using http://is.gd/dskh9 you can get 4.0 blobs on PC while you stay at 3.1.2

Hah for those iPhone3G or ipt2g(non-MC) users at 4.1beta1: use redsn0w from 2 wks ago to JB http://is.gd/dstU3 🙂
