Official DevTeam comments:
RedSn0w
redsn0w allows owners of A4+earlier devices to install rocky-racoon two different ways:
backup/restore method similar to Absinthe and cinject
its traditional limera1n-based ramdisk install. If you have a lot of media on your A4 device (music, movies, TV shows, etc), then the ramdisk method is preferrred because it avoids any possibility of later problems related to syncing to iCloud (including Photo Stream and Music Match). The ramdisk method is not available for A5 devices or later because limera1n can’t be used. If you’d like to use redsn0w’s ramdisk method, just be sure to put the A4 device in DFU or Recovery mode before starting redsn0w (otherwise it will immediately start to use the backup/restore method).
We’ve also added a new redsn0w feature specifically for those who got in on the SAM unlock: you can now include your SAM tickets as part of your initial ramdisk jailbreak of iPhone4 or earlier, or alternatively you can upload your SAM tickets to any device after its been jailbroken. redsn0w accepts either the individual SAM activation ticket plist file, or the entire zip file created by redsn0w’s “Backup” button. As usual, redsn0w continues to cover all of its previous jailbreaks and untethers (so redsn0w-0.9.12b1 covers everything from 5.1.1 all the way back to 4.1).
PwnageTool
PwnageTool also avoids any possible sync issues, but again it applies only to A4+earlier devices. If you unlock your iPhone with ultrasn0w or a commercial method, you must use PwnageTool to avoid updating your baseband otherwise you’ll lose the unlock. PwnageTool will also jailbreak+untether the AppleTV2,1 5.0_2B206f (unless you customize the IPSW further, you’ll have just basic SSH access to the device).
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.
Have you already updated your device to the version iOS4 and want to unlock your 3GS? Firstly there was Redsn0w, now PwnageTool is available, which can easily help you. Here is for jailbreaking iPhone 3GS (old bootrom). Warning: this is not an official release and therefore may be some bugs that can destroy your device or delete some important information. So be careful while using it!
H8sn0w has just released the new version of Sn0wbreeze 1.4. Sn0wbreeze is a jailbreak utility with functionality similar to PwnageTool. The new version supports firmware 3.1.3 jailbreak for the following devices:
Sn0wbreeze is a Windows application, so Mac users have to wait for the upcoming release of PwnageTool by the DevTeam. Alternatively, both Mac and Windows users can use Redsn0w to run jailbreak (no custom firmware though).
You can download the new version of sn0wbreeze .
MuscleNerd continues to argue that we should not use sn0wbreeze. Especially users who have unlocked their iPhone with blacksn0w utility:
iH8Sn0w has released a beta of Sn0wbreeze a software utility which jailbreaks the iPod Touch 1G, 2G and iPhone 2G, 3G, and 3GS (old bootrom & non MC). The software runs on Windows XP, Vista, 7 (32 or 64 bit). Sn0wbreeze is similar to PwnageTool for Mac. It will allow you to create custom ipsws which can be built to include Cydiaapplications and personalized boot logos.
At this time BlackRa1n is still recommended for Windows users with firmware 3.1.2 and RedSn0w for earlier firmwares.
