Apple has fixed Comex's kernel exploit in iOS 4.3.1 closing the door to another jailbreak avenue. Interestingly, his "new" exploit was actually the same one used for JailbreakMe.

As noticed by @0naj, my kernel exploit was fixed in 4.3.1.

I try not to be paranoid, but it is really hard to explain this as anything but a leak.

The funny thing is that my "new" kernel exploit is actually the kernel exploit used by JailbreakMe 2.0. It was never properly fixed.

It stayed there from 4.0.2 through 4.3, but was magically found in time for 4.3.1. well, go go @MuscleNerd and @i0n1c I guess

As usual, we'll keep you informed with the latest jailbreak news as it becomes available.

Does this mean that Comex Exploit can be used to make a jailbreak for Ipads still on 4.3 ? If i have understood this right, they closed it in IOS 4.3.1 but the jailbreak Comex's has discovered will be used/ is possible to still make a jailbreak for Ipad 4.3? In such case, Do you think they are going to release a IOS 4.3 jailbreak?

Your absolutely right... However, need to subtract "yet" from your sentence.

The exploit used in the JailbreakMe 2.0 jailbreak was the PDF exploit which WAS patched in 4.0.2 so I don't understand why he is saying that it wasn't patched.... something doesn't add up here.

He clearly says it wasn't properly fixed. ie Apple missed something when fixing it the first time

He said it wasn't 'properly patched' in the quote above.

It was properly fixed.... if it wasn't properly fixed then everyone could have been using JailbreakMe for their 4.0.2/4.1/4.2.1/4.3 firmwares.

No the PDF part was only the payload method. The underlying vulnerability is probably what he is referring to.
