Jailbreak iOS 5 On iPhone 4.

Due to the extensive work put in by the jailbreak community, we’ve the luxury nowadays of a tether-jailbreak being released simultaneously to the update, and Apple’s latest and greatest version of iOS is no exception. 

 Those of you who have – or are planning to – upgrade to iOS 5 might be pleased to learn that it can be jailbroken (tethered for now), allowing you to add all of those hacks and tweaks you know and love. It has been queried on numerous occasions, with Apple going the whole nine yards in terms of updates, as to whether there would even be any need to jailbreak anymore. 

After all, unless you’re simply stealing apps and games, most of the Cydia tweaks regarding Safari, notifications, SMS etc have all been improved upon, right? Well, while the improvements may appease many into sticking with stock, it’s important to remember that there are some jailbreak apps that just won’t make it to the Cupertino company’s default software bundle. SBSettings is a prime example, bringing control of your iDevice’s vital features using a simple activation method. Thanks to the work of the iPhone Dev-Team, you can tether-jailbreak your iOS 5 device using Redsn0w 0.9.9b5 by following this simple tutorial.

Things to remember: 

• This will not work with iPad 2, nor the iPhone 4S. 
• This is a tethered jailbreak, meaning that it will require you to connect the phone to a computer running Redsn0w whenever you power up the phone. 
• As has been the case before, by pursuing the tethered route, if and when an untethered jailbreak does surface, the chances are you’ll have to restore in order to utilize it.

With that out of the way, let’s get started! 

 Step 1: Download and install the new iTunes 10.5 on your Windows PC or Mac. Connect your iOS device with your computer and make sure you make a backup of everything. NOTE: Those of you who rely on Gevey SIM or Ultrasn0w unlock should skip to “For Unlockers Only” section found at the bottom. 

Step 2: Now upgrade your iOS device to the final version of iOS 5 using iTunes 10.5 on your Windows PC or Mac. Download links for final version of iOS 5 can be found here. 

Step 3: Download the new Redsn0w 0.9.9b5 for Mac or Windows. 

Step 4: Click on the “Jailbreak” option, select “Install Cydia” and follow the onscreen instructions to enter DFU mode. Once you’re in DFU mode, Redsn0w will perform the jailbreak (without having to have you select the IPSW file manually! YES, the new Redsn0w can fetch all the required files automatically from Apple’s servers).

Booting into Tethered-Jailbreak Mode: 

Step 5: Once you’ve installed Cydia, you will need to boot the device into a tethered jailbroken state. Go into DFU mode, and then in “Extras”, opt for “Just Boot”. Redsn0w will subsequently boot your device as tethered. Note: Due to the nature of this jailbreak, you will have to repeat this booting sequence every time you wish to reboot your device.
