During the iPad 2 event, Apple mentioned the iOS 4.3 will be available to all users on March 11. Our recommendation is to stay on iOS 4.2.1 a month after 4.3 is released as all its going to be is a headache.

BigBoss also pointed out the upcoming iOS update will come with an implementation of address space layout randomization (ASLR). Such implementation change will impact the way mobile substrate works. If you haven’t heard of mobile substrate, it is a code library that other tweaks depend on. So if mobile substrate doesn’t work with iOS 4.3, your favorite hacks like WinterBoard, BiteSMS, etc will not work either.

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. Of course we will announce when that is right here.


Therefore, avoid upgrading to iOS 4.3 until a stable jailbreak solution is released.
