Apple didn’t release any tool to fix the exploit currently used for jailbreak. This exploit could be dangerous if you access those dangerous websites. They can get full access of your iPhone so that they can steal your data.
The new instant jailbreak method (jailbreakme.com) we used can also fix the exploit. For those who jailbroken your iPhone already, you can always install it by selecting it from Installer.app. Once you installed, you cannot remove it. (even it show up in the uninstall tab. )
Believe it. Hackers and developers are great. Better than the official Apple.
Was the exploit fixed in the touchfree method, or oyu mean no wiht the jailbreak.com method.
