Apple has closed the PDF security vulnerability which is being exploited by the easiest jailbreak ever at jailbreakme.com and new iDevices are now being shipped with secure iOS Firmware 4.0.2/3.2.2, moments ago the iPhone Dev Team has posted the answer to the obvious question users were thinking of "What Now, will there be a jailbreak for iOS 4.02/3.2.2 ?" and the answer from The Dev team is :

"No, there won’t be. FW 4.0.2/3.2.2 was *only* released to fix the jailbreakme hole. With FW 4.1 still in its beta stages, it makes no sense to escalate the “cat & mouse” with Apple for FW updates that only fix the jailbreak holes. To quote WOPR, “the only winning move is not to play”.

If the cat & mouse game escalates too quickly, especially during beta FW periods, nobody but Apple benefits. For this reason, there won’t be a 4.0.2/3.2.2 jailbreak specifically during the period where 4.0.2/3.2.2 is the latest public release. At best, some future 4.1x FW jailbreak *may* be compatible with 4.0.2/3.2.2 (but don’t count on that).
