That doesn't necessarily mean ANYTHING. It's obviously up there by mistake since no one has gotten ICS OTA and that pdf says it's available and encourages everyone to download it. So if it's existence online is a mistake, it's contents are not verified either. Someone may change that 6 to a 7 and republish that next week.
Plus, what is this header or library that references JB in 247 exactly? Other than the reference what exactly makes anyone think it's necessary for that to be there to get JB? What makes anyone think that it being there actually means we will get JB for sure?? Either of those are assumptions it seems to me. 247 could still come later, perhaps just before any JB release. Or surely JB could still come out even if 247 never does, if that's not true, please tell me exactly why it would NEED that change in 247 to get JB?
