As a Halloween treat, iPhone Dev-Team has released Redsn0w 0.9.6b2 which will jailbreak iOS 4.1 final on iPhone 4/3GS/3G, iPod Touch 4G/3G/2G (non-MC) and iOS 3.2.2 on iPad (Wifi/3G). Redsn0w 0.9.6b2 is based on the same bootrom exploit which has been used in Geohot's Limera1n tool.
Update via MuscleNerd:
Unlike previous versions of Redsn0w, Windows users can use Redsn0w 0.9.6b2 to restore custom IPSW of iOS 4.1 that are cooked by PwnageTool for Mac. Though Redsn0w 0.9.6b2 will jailbreak iOS 4.1 on all the said devices untethered, but it'll upgrade your baseband to 05.14.02 on iPhone 3GS/3G and 02.10.04 on iPhone 4. So all those who rely on an unlocked phone should stay away from Redsn0w and should use PwnageTool 4.1 instead. If you don't rely on an unlocked phone, use the guide below to jailbreak your device on Windows and Mac OS X with Redsn0w 0.9.6b2.
