Just updated - works fine for me. iphone 4, 4.3.2, redsn0w 0.9.6rc14
I thought I read somewhere the new version uses a different way of checking for a JB and there is no fix out yet for it.
This is incorrect. DRM protected books in iBooks work just fine under jb 4.3.2.

Either the fix is included in redsn0w 0.9.6rc14 or I have a magic phone 4.
That Twitter post was written by a well-known member of the jailbreak community who has provided you with a previous jailbreaks as well as the previous Cydia iBooks fix for 4.2.1.
It's not like he's just some random Twitter spammer I happened across...
Instead of starting a new thread, I'm adding to this one.
Running 4.3.3 jb with the latest redsnow. iBooks crashes when trying to go to the Store. I deleted and reinstalled iBooks and it synced fine, but crashes every time I tap on Store.
Running the exact same setup but it works fine here. Perhaps try and (re-authorize?) your iTunes account by login and logout of the Store under Settings
