Success going from 1.0.1 autonootered (not the latest version, I rooted a couple days before the last release) to 1.1.0 via this method. I have not had any issues at all. I think those that have had problems are using this method from rooted 1.0.0.
I'll have to go to BN tomorrow and see if read in store works....
....I've never actually read in store, but for those expiring library books, might as well finish the book for free in BN....
