One thing to keep in mind is often updates are hurried up to Fix Problems with the phone. I haven't heard of Any of these systematic issues with the Spirit to require fixing with an update. I don't understand JB to give us any new real Features the phone doesn't already have. My life will not be any more complete with a dancing or flying Jelly Bean icon than it will a flying Ice Cream Sammitch.
I think at least as many updates with the Motion were to lock us users Out More than they were to Fix any real operational issues.
When the manufacturers stop shipping out new phones they already know have serious issues it becomes not so urgent an issue they do an update to correct the problems that aren't there.
