You have been waiting for that! MuscleNerd has just said that comex will try to pull a trifecta by releasing a userland jailbreak similar to JailbreakMe (http://www.coveringweb.com/2010/08/download-jailbreakme-to-jailbreak.html) to jailbreak iOS 4.1 (http://www.coveringweb.com/2010/09/ios-41-gm-full-coverage-updating.html) for all devices but if he fails to do though, then a iBoot or bootrom exploits will be released.

Stephanos asked MuscleNerd about the type of iOS 4.1 jailbreak, userland jailbreak or a software jailbreak which runs under Windows / Mac
@MuscleNerd I know tons already asked this but is the iOS4.1 gonna be a userland jailbreak as usual or will redsn0w be making a comeback?
MusclNerd replied to him saying that Comex will release a userland jailbreak if he could pull trifecta
@TechXero it'll be userland JB if @comex can pull trifecta. Else, wait for new HW cycle (also remember: hole!=exploit)
There's no ETA but all what we know that the iPhone Dev Team are working hard on jailbreaking iOS 4.1 for all devices. If they failed to do though, they will release the ready-done jailbreak for iPhone 3G / 3GS (old bootrom) and iPod touch 2G / 3G (Non-MC models). For others, you may wait until iOS 4.2 (http://www.coveringweb.com/2010/09/apple-posts-ios-42-for-ipad-details.html) release in November.
