I am running IOS 4.3.3 on my touch. I tend to stay away from betas b/c their problems are a bit above my tech level
I could not reboot my touch, so I ended up deleting and reloading Stanza. After reloading all of my books (and boy did THAT take a long time *sigh*...only 6 books at a time, really itunes?!?!?), it appears to be working fine.
Thanks for all the helpful comments!!!!
