As promised, iPhone Dev team announced Redsn0w 0.9.7b1 untethered jailbreak for iOS 4.2.1. Redsn0w 0.9.7b1 jailbreak is designed to work with iPhone 4, iPod Touch 4G and Apple iPad. Those who are using iPhone 3G, iPhone 3G S, iPod Touch 2G on iOS 4.2.1 already have a fully working untethered jailbreak with Redsn0w 0.9.6b6. As you might know, an untethered jailbreak let you restart your device to jailbreak mode, without the need of connecting the device to a computer. Redsn0w 0.9. 7b1 download released today is intended for Mac users who are interested in helping the dev team in testing the jailbreak for any bugs.
These are the requirements for running Redsn0w 0.9.7b1.
An Apple iPhone 4, iPod Touch 4G or iPad with iOS 4.2.1 installed.
RedSn0w is always available for both Mac OS X and Windows at the same time, so no usergroup is left in the dark. Yet another advantage to the RedSn0w Jailbreaking tool is that it encompasses so many additional features. Nowadays RedSn0w really is your go-to tool for everything Jailbreaking related. The first thing you will need to do is download RedSn0w v0.9.15b1 for the Mac OS X or Windows.

This version of Redsn0w is a little unstable, and therefore, some device options may stop working after jailbreak. So normal users and those who rely on the Ultrasn0w unlock are not advised to use this jailbreak. Redsn0w 0.9.7b2 or the upcoming versions of the tool would be able to process the untethered jailbreak with locally saved Signature Hash files and without usbmuxd.
Update: Download Redsn0w 0.9.7b3 here. (Install Redsn0w 0.9.7b3 after a fresh restore with iOS 4.2.1)
Bugs fixed: Native app crashes with Redsn0w 0.9.7b2, Issues with embedded videos and FaceTime with Redsn0w 0.9.7b3.
Update: Download Redsn0w 0.9.7b4 here. Now you don’t need to use usbmuxd and any related command part for jailbreaking. Just follow the other steps given in the tutorial and finally use Redsn0w 0.9.7b4 for untethered jailbreak.

Download Redsn0w 0.9.2, the ultimate Iphone Jailbreak and Unlock tool! It is a cross-platform (works on windows and Mac OS X) jailbreaking, unlocking and customizing tool for iPhones and iPod touches. Customizations include boot logos, recovery logos, and “verbose” boot. It’s a standalone program that doesn’t use iTunes (no custom IPSWs are involved).
What is cool about Redsn0w is it doesn’t require a system restore like PwnageTool and it doesn’t even use Itunes. PwnageTool can prevent your baseband from being upgraded when you upgrade your firmware, preserving your unlock. Redsn0w doesn’t touch your baseband but it doesn’t help preserve it during an upgrade either. So, how does it really work? redsn0w works by modifying your current filesystem, so your existing baseband, data and applications should remain intact.
Redsn0w 0.9.2 supports the following devices.
- All iPhones and iPod touches (still a tethered-only JB for late-model devices though)
- Apple firmware 3.0 and 3.1.2
- Windows and Mac OSX (x86 only for now)
- It will also soon run on the PPC OSX, and Linux platforms.
If you need a carrier unlock, redsn0w will handle iPhone 2G by itself by installing the BootNeuter utility. For the 3G and 3GS, use Cydia after you’re jail-broken to install ultrasn0w (baseband 04.26, preferred) or blacksn0w (baseband 05.11).
Dev Team has the following advice.
DO NOT USE REDSN0W AFTER DOING A STOCK APPLE UPGRADE TO 3.1.2 IF YOU NEED A CARRIER UNLOCK AND ARE CURRENTLY USING BASEBAND 04.26 OR EARLIER. The key part of that advice is “do not do a stock Apple upgrade to 3.1.2”. You really want to keep that 04.26 baseband on there because then you can keep using ultrasn0w. Ultrasn0w doesn’t have the wifi issues that some people (10-20%) report when using geohot’s blacksn0w unlock on 05.11. If you are at 04.26 or earlier, use a custom IPSW from PwnageTool to update your firmware to 3.1.2, or just stay at 3.0 and use redsn0w there (redsn0w and ultrasn0w work on both 3.0 and 3.1.2, but ultrasn0w needs baseband 04.26).
A few limitations for late-model iPhone 3GS
If you have a late-model iPhone 3GS or if you have an iPod touch 2G whose serial number begins with “MC” or any iPod touch 3G, you can use redsn0w to jailbreak but you are currently restricted to “tethered” rebooting. Thus you need to connect your device to a computer to complete the boot after a reset. Also, these devices cannot have custom logos.
Redsn0w will ask you whether or not you fit in this category when it is used with the iPhone 3GS or iPod touch. If you have a late-model device and don’t give redsn0w the correct answer, you will likely need to do a system restore to recover from the mistake.
To do a tethered boot after your late-model device resets for some reason, either run redsn0w again and select “Just boot tethered right now”, or run blackra1n.
If you’re already jail-broken (by whatever means), redsn0w can still be used to change your boot logos, revert back to the stock logos, or switch verbose booting on and off. By selecting “Already Pwned” you can bypass the steps normally needed to enter the jail-broken state.
How long does the whole process take?
You should see a picture of a drive (“Downloading Jailbreak Data”) within 30 seconds of launching the jailbreak (after you’ve made your custom selections). It should then reboot and you should see a running pwnapple while the process is underway. It should finish within a minute or two after that and will reboot on its own.

IPCC tethering hack and redsn0w 0.9.3
IPCC tethering hack allows you to install cellphone Carrier Bundles that aren’t officially signed by Apple. This lets you, for instance, install a Carrier Bundle that allows you to use your iPhone as a way to connect your PC to the internet (through your 3G cell connection). This hack is always installed on 3G and 3GS phones by redsn0w 0.9.3 (no selection is required). It isn’t included at all in 0.9.2 (it’s still in a trial phase). Note that carriers may not like you tethering behind their back so you do so at your own risk.
