So it turns out that the first working iPad 3.2.2 Jailbreak won't be coming from Comex.
UPDATE as of October 10, 2010, 3:38 PM, Manila Time:
LimeRa1n jailbreak has completely upstaged GreenPois0n. Learn how to jailbreak iPad 3.2.2 with LimeRain via the link.
Upon its release at exactly 10:10:10 AM GMT today (that's 6:10:10 PM, Manila Time), greenpois0n - a creation of Chronic Dev Team - will be the first and, as yet, ONLY working jailbreak for iPads running 3.2.2 firmware.
TP will update this post as soon as we get the download link from Chronic Dev Team. Hopefully, they'll also release a step-by-step guide on how to use the jailbreak.
Note that jailbreaking any iDevice voids its Apple warranty and makes it vulnerable to worms and viruses. Likewise, improper jailbreak procedure can brick an iDevice. Use greenpois0n and follow the jailbreak guide at your own risk.
