Hey pod2g is having a pool about releasing JB or saving the exploits for ios 6 go vote I voted for the wait I would like iOS as fast as possible JB then have to wait but then I again I want JB too lol so go vote
If the kernel-land vulnerability is exploitable, it would mean that all current devices will be susceptible to at least a tethered jailbreak for life(like A4 and lower devices are currently).
