iPhone 3G, iPod Touch 2G and iPhone 4 Verizon do not have iOS 4.3 update.
UPDate: 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.
UPDATE: Please, consider reading our Jailbreak & Unlock FAQ, especially if you have questions or troubles.
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:
DevTeam released PwnageTool 4.2 utility. It is able to create a custom IPSW that can perform an untethered jailbreak on iOS 4.2.1. As usual it can preserve baseband version for unlockers. Devteam used the same method that was implemented in greenpois0n.
PwnageTool supports all 4.2.1 devices other than iPod touch 2G:
iPhone3G
iPhone3GS
iPhone4
iPhone4-Verizon
iPod touch 3G
iPod touch 4G
iPad
AppleTV 2G
Jailbreak is even improved compared to GreenPois0n RC6:
Apple today has posted iOS 4.2.6 for Verizon iPhone on its servers for public download, where it listed as for iPhone 3,3, the identifier for the CDMA version of iPhone 4. The version checks in as Build 8E200. Possibly the firmware was launched for journalists who have reportedly received the devices to write reviews. The Verizon iPhone carried iOS 4.2.5 when it was demoed at the media event introducing the device earlier this month, so it appears that Apple has made some additional tweaks since that time. Those who hoping that iPhone 4 for Verizon would be released with the iOS 4.3 will no doubt be disappointed. Though, it is pretty likely that 4.3 is going to be ready quickly after launch of the device.
Good news everyone. DevTeam recently posted a tweet where they inform us that they will soon release a new version of Redsn0w utility for Windows. It will be an untethered jailbreak for iOS 4.2.1 using the Monte iOS 4.1 technique.
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.
UPDATE: Please, consider reading our Jailbreak & Unlock FAQ, especially if you have questions or troubles.
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.

These are instructions on how to jailbreak and unlock your iPhone 3GS on iOS 4.1 using PwnageTool 4.1.3 for Mac OS X. This tutorial will explain how to upgrade your baseband if needed for an unlock.
There is no unthethered jailbreak for new iPhone 3GS bootroms and iOS 4.2.1 yet, so you should stay at iOS 4.1.
Important: iPhone3GS users with old bootroms who want to go to 4.2.1 and unlock should not use this PwnageTool! Update to stock 4.2.1 first, then use new redsn0w to update your baseband.
Step One
Make a folder called "Pwnage" on the desktop. Download a couple of things:
The iPhone Dev-Team has released RedSn0w 0.9.6b5 for unlockers stuck at the 05.14 or 05.15 basebands.
The new redsn0w 0.9.6beta5 is out. It gives both Windows and OSX users the ability to flash the iPad 06.15 baseband on iPhone3G or iPhone3GS. It fetches the baseband files directly from Apple for now (the only IPSW you ever point it at is the stock IPSW for the FW on your iPhone right now). There may be a long delay while it’s doing this (their servers are currently getting pounded).
UPDATE: Обязательно (!) думайте перед тем, как что-нибудь сделать. Читайте внимательно и еще раз думайте. Не понятно - читайте снова. Спрашивайте до, а не после.
UPDATE 2: Если у вас 05.13 baseband и ниже - она ломается старыми способами, не надо обновляться до 05.14, 05.15 и 06.15. Хочется перейти на 4.1/4.2 - тогда делайте кастом прошивку с помощью pwnagetool.
UPDATE: Please, consider reading our Jailbreak & Unlock FAQ, especially if you have questions or troubles.
Данное пошаговое руководство позволит вам сделать джейлбрейк и анлок iPhone 3G на iOS 4.2.1 с помощью PwnageTool 4.1.3 под Mac OS X. Здесь также будут даны инструкции по обновлению baseband, если это необходимо для анлока (отвязки от оператора сотовой связи).
DevTeam worked hard for the last several hours and released jailbreak tool for iOS 4.2.1. It is redsn0w 0.9.6 b4.
As usual we remind all ultrasn0w unlockers please stay away from this official firmware. Wait for the ability to create custom 4.2.1 IPSWs that don’t update your baseband!
New redsn0w 0.9.6 b4 uses limera1n exploit and will successfully jailbreak all devices. The only problem is that it is a tethered jailbreak, which means you will have to plug it to a computer and rerun redsn0w on every reboot. This so called tethered or semi-tethered jailbreak. This condition applies to iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC model), iPod touch 3G and iPod touch 4G. Hackers are working hard to create untethered jailbreak for these devices. To use future untethered jailbreak you need to save SHSH keys for iOS 4.1 using TinyUmbrella utility or directly in Cydia.
Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC model) can be jailbroken-untethered right now using this latest version of RedSn0w.
Apple finally released iOS 4.2 for iPhone 3G/3GS/4, iPad, iPod Touch 2G/3G/4G and even Apple TV 2G. Lot's of new features, especially for iPad. Apple calls new firmware 4.2, however the version is actually 4.2.1. Here are the download links:
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).
Just a day after PwnageTool 4.1.1 release, DevTeam created one more update for popular jailbreak utility - PwnageTool 4.1.2 for Mac OS X. This release should solve some problems that users had. However there are still users reporting iTunes errors when restoring custom firmware. Anyway PwnageTool 4.1.2 is worth trying.
