I'm experiencing the same problem on second Kindle, this folder doesn't exists
I don't know what I did previously to create/show it, but the situation is the same, and
doesn't show this folder.
This Kindle is freshly after JB, JBPatch, JBKindlet. I had run webrowser, so maybe it would create webkit-1.0 folder, made reboot, but it's still not there.
Any ideas?
