No... iBooks REMOVES your books from iTunes management software ... iTunes still syncs them to devices, but it no longer has access to the books to add/change metadata and such. (and iBooks also has no ability to do that.)
I see you decided to just make stuff up, since you have no actual knowledge about it. I never said it wouldn't work fine for YOU... just related my own experience with it. I know what the problem is, and the cellular network works much better IN MY CASE. For me, iMessage is unusable... "Sucks" seemed to be an adequate descriptor.
His problem wasn't with syncing ... it was that the transition from iTunes to iBooks lost his "books" (or so I understood it.) As for reading what the new stuff does ... NOWHERE did Apple tell us that iBooks would completely re-name files (to gibberish) and strip any meta-data that we had added to non-iBooks-store material that we had in our iTunes Books library. iBooks works fine as a reader for iTunes-purchased books... but it really is half-assed as a replacement for...
I will go on record saying that iMessage SUCKS.
Using cellular texting, speed and reliability seems to be very near 100%.
If I turn on iMessage, then speed goes from near-instantaneous to several minutes for a text to arrive at its destination. Assuming it arrives at all... among the six phones on my family plan, iMessage has a reliability of maybe 80%... meaning 20% of texts never even made it to the destination! Needless to say, I've turned iMessage OFF on all of...
If his iPad is NOT cellular, then the only way it can be "located" is if it is on a WiFi network that is contained in whatever location database(s) Apple uses for this. Most personal WiFi networks will NOT be included in such a database ... so seeing it as "online" but "unable to locate" is not that unusual.
you can't log into iCloud from Safari on iOS ... but perhaps with a different browser?
... I haven't tried it, so it might not work... but try a different browser and see if you can log in.
(I think Dolphin is free if you need to find one real quick... i also think Chrome might be available for iOS.)
I was SO glad I had a backup of those iTunes book files after migrating to iBooks OSX. I use those files on other stuff... not just t sync with iOS devices... the placement I could have lived with, but the gibberish names pissed me off.
I guess I'll stick with Stanza for reading on the MacBook... (at least for now.)
