The untethered jailbreak tool evasi0n for iOS 6.x which has been downloaded by over four million users has seen a bit more news come out over the past 24 hours, led by an update designed to address a pair of bugs discovered in the initial version.
Jailbreak author pod2g has also noted on Twitter that Apple's just-released iOS 6.1.1 beta does not yet address any of the bugs used by evasi0n in the jailbreaking process. This may change in future betas, however, and evasi0n is not currently designed to work on iOS 6.1.1, so users interested in jailbreaking their devices should hold off from updating.
