Its here folks! and its real!! Geohot is back big time with limera1n jailbreak for all iOS devices including: iPhone 4, iPhone 3GS, iPad, iPod touch 4G / 3G / 2G, untethered running iOS 4.1.
NOTE: If you rely on an unlock, do not update to iOS 4.1 without using http://thefirmwareumbrella.blogspot.com/ , as doing so will upgrade your baseband, making it impossible to unlock (for now). TinyUmbrella will enable you to update to iOS 4.1 without updating your baseband.... here is a tut how to use tinyumberella http://www.redmondpie.com/upda…59.00-baseband-to-2.10.4/
Here is a tutorial to help you along with installing limera1n
