Jailbreak iOS 5 GM with Redsn0w 0.9.9b3

Soon after the news of impending release of the much-awaited iOS 5 Gold Master (GM) by Apple, followed the much anticipated confirmation from the iPhone Dev team – as MuscleNerd tweeted that iOS 5 GM jailbreak can be done using the latest version of Redsn0w.

All you need to do to execute this tethered jailbreak is download redsn0w 0.9.9b3 (or up) for Mac or 0.9.9b3a (or up) for Windows; connect your iPhone, iPod touch, or iPad to your computer with a USB cable and run the jailbreaking software. Recent reports suggest that Redsn0w should work with all devices that can run iOS 5 excluding Apple’s newest tablet, the iPad 2.

Here is the Step-by-Step Guide to Jailbreak iOS 5 GM

1. Download Redsnow 0.9.9b4 (Windows / Mac)
2. Click the “extras” option and then select “IPSW” to manually point Redsnow to the iOS 5 beta 7 firmware to jailbreak iOS 5 GM.



3.    Go back and then click the option to “Jailbreak”.
4.    Select “Install Cydia” and follow the instructions to enter DFU mode.
5.    Once there Redsn0w will load the limera1n exploit to tether-jailbreak your iOS device on iOS 5 GM.

At the mean time, iOS 5 GM is only available for registered iOS developers. If you haven’t yet tried the iOS 5 GM jailbreak, I’m sure you would definitely like to try it out when Apple launches the version on October 12, 2011. That’s tomorrow!

How to Fix the Quarter Screen Issue

However, as the jailbreaking community enthusiastically awaits the arrival of the D-day, there are certain ‘whispers of impending problems’ with the iOS 5 jailbreak. A jailbreak app called “Activator” has been identified to cause applications to display in a quarter of the iOS 5 loaded iPhone’s screen. The problem aptly connoted the “1/4 Screen” problem reports that when Activator (via Cydia) is installed on a jailbroken iPhone that is running the latest iOS, the App size is found to run at a reduced size, roughly one quarter of the screen.

As of now, the “1/4 Screen” problem is said to have been temporarily fixed; i.e. every time you reboot your iOS device, a repeat of the process is inevitable. Here’s a quick-fix solution:

Open SBSettings > Tap “Power”, and select “Safe Mode” > (Once booted into Safe Mode)
Tap the status bar when it says “Safe Mode”. (This will bring up a prompt)
Tap “Restart” to restart into normal mode > Launch an offending App – the error is expected to be resolved.
Many more developments are anticipated to unfold in the coming days as more iPhone app developers (including jailbreak developers) and users alike update their apps for the upcoming software update.
