The iPhone Dev-Team released a tethered jailbreak for iOS 5 beta 1 yesterday. Here’s our full tutorial to help you jailbreak iOS 5 on your iPhone, iPod Touch or iPad. Please note that you will need to still have a valid UDID registration in order to be able to activate and use iOS 5 fully.
In case you haven’t installed iOS 5 beta on your device yet, you should first read our iOS 5 install guide. Like always we are warning iPhone users to first backup their data as well as SHSH blobs since this is beta software and both the iOS 5 firmware and RedSn0w are not perfect at the moment.
This tutorial is meant for Mac users only. A windows version of Redsn0w 0.9.8b1 is in the works and will be released soon. Devices compatible with this release of redsn0w are iPhone 4, iPhone 3GS, iPod Touch 3G and 4G and iPad 1. Since this is a tethered jailbreak, you will have to use Redsn0w everytime your iOS device reboots.
Tools required to Tethered Jailbreak iOS 5 Beta 1 with Redsn0w 0.9.8b1:
Download these files first before proceeding with the jailbreak procedure.
How to tethered Jailbreak iOS 5.0b1 using Redsn0w:
Quit iTunes first. Unzip the Redsn0w archive and launch Redsn0w.
Click on browse and point Redsn0w to the iOS 5 firmware file corresponding to your iOS device. Once Redsn0w has identified the firmware click on next and it will start preparing jailbreak data. This takes a minute.
On the next screen just make sure Install Cydia is checked and hit next.
At this point you will be asked to connect your device to your Mac and switch it off.
Once you have done that click next and you’ll see instructions to place your iPhone into DFU mode. This is essential for jailbreaking the iPhone.
Once placed into DFU mode, Redsn0w will start the jailbreak process. When Redsn0w says done don’t click Finish yet. Click back instead and wait for your iPhone to restart.
Now check Just boot tethered right now and click on next. Once again you will have to put the iPhone into DFU mode. This is the step that you need to repeat every time the iPhone reboots.
This time you can hit finish. The iPhone will have Cydia installed.
Not all Cydia applications work well on iOS 5 at the moment. We’ll soon post a list of jailbreak tweaks that are compatible with iOS 5 beta 1.
