Apple is planning to release a software update to patch the PDF security hole that allows comex’s jailbreak to work. This means that upgrading to this newer firmware will render the jailbreak useless until a new exploit is found. (Although, comex doesn’t seem too worried.)
“We’re aware of this reported issue, we have already developed a fix and it will be available to customers in an upcoming software update.”
If you’re planning to purchase and jailbreak a new Apple gizmo, you better do it now because the patch will probably be shipping with new units.
If you want to stay relatively safe without sacrificing your jailbreak, try out this fix, and don’t go to any sketchy looking websites.
