Apple Releases iOS 4.3

Today, Apple has released iOS 4.3 for iPhone, iPod touch, and iPad.

At the moment, it is not recommended to jailbreak your device on iOS 4.3 because it uses address space layout randomization or ASLR which will cause MobileSubstrate not to work. This would mean that you can’t run any tweaks that use MobileSubstrate (SBSettings, Music Controls, Lockdown, WinterBoard, etc.) until an update to MobileSubstrate has been released, fixing the incompatibility.
