The iPhone Dev-Team released jailbreak utility RedSn0w 0.9.9b6 for both Windows and Mac users. The new version offers full iOS 5 jailbreak support for Windows and fixes Location Services issue for iPhone 3GS devices running the 06.15 baseband. This is still a tethered jailbreak for iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G and iPod Touch 4G:
We’ve released version 0.9.9b6 of redsn0w, with both a functional fix and cosmetic fix for iOS5 jailbreakers. For iPhone3GS owners with the 06.15 baseband, this redsn0w eliminates the network crash you saw when using Location Services in iOS5 (in fact, you don’t even need to disable Location Services anymore during the initial setup). The cosmetic fix is to the visual countdown you see when going into DFU mode.
It’s okay to re-run this redsn0w over an existing device jailbroken at iOS5. Just choose “Jailbreak” again and de-select Cydia (in other words, all the checkboxes will be unchecked). If you are lucky enough to have an old-bootrom iPhone3GS, please pre-select the IPSW first (redsn0w can’t yet auto-detect the FW version of your old-bootrom 3GS if it’s already been jailbroken).
Just as redsnow 0.9.9b5 the new version supports creating custom firmwares with preserving baseband (modem) version for unlock. Unfortunately right now custom firmware functionality works only with Mac version.
UPDATE: Apple latest firmware is iOS 5.1.1. Apple has stopped signing all other firmwares, including iOS 5.0.1, iOS 4.3.3 and iOS 4.3.5. This means you can NOT restore to 5.0.1/4.3.3/4.3.5 any more (both original and custom), unless you have saved your SHSH keys for it.
If you have decided to perform an untethered jailbreak and unlock, you need to get the following information:
What type of device do you have (iPhone 3G/3GS/4, iPod Touch 3G/4G, iPad 1/2, Apple TV)?
Do you need unlock (if your iPhone locked to one carrier and you want to use it with another)?
The answer is NO, if the device is not iPhone, if it was purchased as factory unlocked and can be used with any cellular carrier (f.e. in Canada, France, etc).
If the answer is YES, you need to find out your modem version (Setting-General-About-Modem).
What firmware version do you have? Take a look at Setting-General-About-Version. For example it could be iOS 4.3.3.
What operating system do you use on your desktop (Windows, Mac OS)?
How to perform jailbreak, when you do NOT need an unlock
For iPhone 3G the latest is iOS 4.2.1. You can perform jailbreak with any utility. For iOS 4.2.1 you can also use them or GreenPois0n (Windows, Mac OS).
iPad 2 jailbreak is available only for iOS 4.3.3 via JailbreakMe and and iOS 5.0.1 via Absenthe.
iPhone 4S jailbreak is available for iOS 5.0 / iOS 5.0.1 via Absenthe.
iOS 4.3.3
Apple stopped signing iOS 4.3.3, so you cannot update to iOS 4.3.3 without SHSH keys saved (in advance some time ago). If you have iPhone 4, iPhone 3GS, iPad 1, iPod Touch 3G or iPod Touch 4G that run iOS 4.3.3 – use JailbreakMe or RedSn0w to untether jailbreak your device.
If you have saved SHSH keys for iOS 4.3.3 you can use PwnageTool (Mac OS) or Sn0wBreeze (Windows).
iOS 4.3.4/4.3.5
For iOS 4.3.4/4.3.5 only tethered jailbreak is possible with redsn0w. Tethered means that each time you restart your device you will have to connect it to a computer and run redsn0w. The untethered iOS 4.3.5 jailbreak is possible only for iPhone 3GS with old bootrom. You can detect your bootrom version using this tutorial.
iOS 5
To jailbreak and unlock iOS 5 use latest version of redsn0w 0.9.9 or sn0wbreeze 2.8. You can jailbreak tethered or semi-tethered.
The untethered iOS 5 jailbreak is possible only for iPhone 3GS with old bootrom. You can detect your bootrom version using this tutorial.
iOS 5.0.1
For iPhone 4/3GS, iPad 1, iPod Touch 3G/4G an untethered jailbreak is available for iOS 5.0.1. For untethered jailbreak use the latest redsn0w 0.9.10 or Corona – package from Cydia to untether currently installed tethered jailbreak.
Tutorial how to untether installed tethered jailbreak is available here.
For iPhone 4S and iPad 2 use Absenthe.
For tethered iOS 5.0.1 jailbreak you an use redsn0w 0.9.9 and sn0wbreeze 2.8.
iOS 5.1 / iOS 5.1.1
For now only tethered jailbreak is available for iPhone 4/3GS, iPad 1 and iPod Touch 3G/4G for iOS 5.1 and iOS 5.1.1.
iH8Sn0w released Sn0wBreeze 2.8b7, which adds jailbreak support for the latest iOS 5 beta 7 firmware.
Sn0wBreeze creates custom firmware and allows users to preserve baseband for unlock (ultrasn0w doesn’t work with iOS 5 yet). This new version also adds hacktivation and removes UDID developer check. This means that you can try iOS 5 without developer account from Apple.
You can download Sn0wBreeze 2.8b7 for Windows here.

ULTRASN0W USERS:
————————————————————————-
There is a temp. fix available on Pushfix’s Cydia repo (http://cydia.pushfix.info)
for getting ultrasn0w to work on preserved basebands on 4.3.1.
[It does not fix the iPhone 4 single bar issue though!]
————————————————————————-
UPDate 2: Attention! We’ve received info, that Apple stopped signing iOS 4.2 for devices for which iOS 4.3 is available. This means you will not be able to restore to 4.2.1 without saved SHSH keys.
Using this tutorial you will be able to jailbreak iOS 4.2.1 running on iPhone 3G, iPhone 3GS, iPhone 4, iPod Touch 3G, iPod Touch 4G and iPad. Pwnagetool will also preserve baseband version if you need carrier unlock. If you have updated the baseband to version 06.15, you can use this tutorial. This tutorial uses PwnageTool 4.2 for Mac OS X.
We are not developers of jailbreak utilities, so we cannot assure that everything will work just fine. However we tried this tutorial on several devices and succeeded.
We will use iPhone 4 in our jailbreak tutorial. The process is the same for all devices.
Step One
Make a folder called “Pwnage” on the desktop. Download a couple of things:
Apple stopped to support original iPhone 2G and iPod touch 1G starting from iOS 4.0. Their decision was justified because of the low RAM and sow CPU in these first-gen devices released back in 2007.
iPhone jailbreak community has now come up with a mod, which brings the complete look and feel of iOS 4.2.1 for iPhone 2G, 3G and iPod touch 1G and 2G. The mod is basically based on the iPhone OS 3.1.3, to replicate the experience of iOS 4 on the first and second generation iPhone and iPod touch.
This custom firmware, named WhiteD00r, includes everything from iOS 4.x: wallpapers, new semi transparent dock (and UI), backgrounds, all new icons from iOS 4.x, Voice Control, multitasking, video recording, and more. Full list of features can be found here.
Moreover WhiteD00r was also relased for iPhone 3G and iPod touch 2G. Regular iOS 4.х works really slow, on these devices, while modified 3.1.3 has much more chances.
WhiteD00r custom 4.2.1 firmware for iPhone 2G, iPhone 3G, iPod touch 1G and iPod touch 2G can be downloaded from here.
If you have an iPhone 3GS with the new bootrom you will only be able to perform a tethered jailbreak at this time. This means you will need Redsn0w’s assistance to boot into your jailbroken device.
IMPORTANT FOR UNLOCKERS
During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.

The iPhone Dev-Team recently has released a new version of RedSn0w for Mac and Windows. RedSn0w uses the Limera1n exploit to support more devices and adds the ability to restore custom firmware ipsws. The crew promises that now RedSn0w will work with the iPhone 3G, 3GS, 4, iPad, iPod 2G, 3G, and 4G (Not iPod 2G-MC yet).
