Fix Mobile Substrate in Cydia After iOS 4.3 Jailbreak

Once a user jailbreaks the iOS 4.3, he manages to force the ASLR (Address Space Layout Randomization) feature which was implemented in the new iOS 4.3, to break the Mobile Substrate in Cydia, which is needed by many other tweaks and add-ons available in Cydia.
It is because of this update, that you will now be able to install and use all of the jailbroken apps and tweaks on the iOS 4.3 without any error or bug.


What You Need:

1. Jailbroken iOS device on iOS 4.3
2. Basic knowledge of jailbreaking

Instructions:

Now, the very first step is to open up Cydia from your “Homescreen” and go to the Search tab from Cydia, and search for “Safari Download Manager” and “iFile” for your respective iOS device and install both these apps

Now once you have downloaded both the apps, navigate to the below given link from your iOS device Safari browser

• http://apt.saurik.com/debs/mobilesubstrate_0.9.3367+6.g629fcfa_iphoneos-arm.deb

The Mobile Safari browser will prompt you if you want to download the file or not, click on the “Download” button and download the following file directory

• .deb file to: /var/mobile

Now, go and start the “iFile” application and navigate to the place where you downloaded the above file directory. Tap on the Mobile Substrate.deb file and tap on the “Install” button to start the installation process
Once done, just give your iOS device a reboot to make sure things progress successfully. Now, once the reboot is complete, start Cydia again and search for “Mobile Substrate” and you should have the latest version for the iOS 4.3
