Numerous tutorials are popping up online which provide instructions on how to jailbreak the new iOS 4.3 GM Seed posted to developers. BigBoss has issued a warning asking users not to update to and jailbreak this firmware.
As always, I give my standard warning not to update and wait for the jailbreak release. This time, I am giving some extra caution, however.
With 4.3 comes apple’s implementation of address space layout randomization (ASLR). In short, this will mess up the way mobile substrate works. You will need a new mobile substrate in order to use your favorite tweaks such as winterboard, sbsettings, bitesms, folder enhancer, etc. So you should definitely avoid 4.3 until an “official” jailbreak is released for it.
As usual we will provide detailed tutorials to help you get all your devices jailbroken once the firmware and jailbreaks are available.
