How To Fix Mobile Substrate in Cydia After iOS 4.3 Jailbreak [Guide]
The following step by step guide will help you fix Mobile Substrate issues in Cydia after jailbreaking iPhone, iPad or iPod touch on iOS 4.3.
For those of you who don’t know, Apple implemented ASLR (Address Space Layout Randomization) in iOS 4.3 to make iOS devices more secure against vulnerabilities, such as the one demonstrated at the recent Pwn2Own contest. This ASLR implementation unfortunately also resulted in breaking Mobile Substrate which is an essential component for many tweaks and add-ons available on Cydia.
Now with this new update (thanks to FSM for the find) to Mobile Substrate by Saurik, ASLR issues have been reportedly fixed, which means that you can now install your favorite apps and tweaks from Cydia on your jailbrokeniOS 4.3 based devices.
