Well, it went smoother than expected. I've copied the update bin to the device, just to be sure. To have it in place once I obtain the sequence confirmation. Well, the device did not asked me how and when I want to apply the update, it did it sometime in the day. I find it a bit spooky. Nex time there will be no bin files hanging around until I get the green light.
Anyway, the JB mobi worked like a charm, thanks again. You are the greatest.
