Looks like anyone waiting on the iOS 5.1 untethered jailbreak could be waiting longer than first thought. @i0n1c who displayed the untether on YouTube on the day of release of the latest iPad has stated on twitter that he will not be releasing it. :( Although @MuscleNerd and a collaboration between @chpwn & @phoenixdev also stated that they had jailbroken the new iPads using doiferent methods these were not untethered. For these to become the untethered jb everyone is hoping for will i'm sure take a lot more work before general public release. As always if you rely on your jailbreak then obviously do not update to 5.1 til one of the above mentioned devs releases their new jb. Follow them on twitter to keep up to date. You never know @i0n1c may have a change of heart and release his although i wouldn't hold my breath.
