Bottom line?
It's not out. No one knows EXACTLY at this moment.
Don't rush into installing it the very second it becomes available - ESPECIALLY IF IT IS ON YOUR
ONLY PHONE. Wait a bit, have a little patience and see what gets reported by actual users on actual phones using the actual Preview. Rumors are rumors and by their very nature full of speculation that may or may not be factual.
There is no factual information to provide... It's all theoretical and rumor based at this date and time.
