It was clear to everyone with even half a brain-cell that 3.56 would only be a temporary solution and a proper firmware would come out a bit later. That's exactly why jailbreaking 3.56 didn't really make any sense. 3.60 on the other hand will be around for longer and as it even adds a properly useful feature it's fairly possible a CFW will appear within 2 months.
As for getting online: well, we'll only see it when the maintenance is over, but I actually have a gut-feeling that you only need to change 3.56 to 3.60 in ****PSN or Charles and you'll be good to go.
