Didn't see AT&T Note 3 being mentioned in that first post of geohot. It does say that any kernel before June could be rooted, but I wouldn't take that as a confirmation just yet, although very excited.
Device: Samsung Galaxy Note GT-N7000 (international)
ROM: Criskelo 4.0.4 ICS ROM XXLRK v11.2
Kernel: speedmod k 3-13
