Does not appear when? Did you do what I suggested? When you say it doesn't appear as a choice, we don't know what you are referring to. You don't have to open the PDF in order to get the Open In Box. Are you even getting the Open in box?
If you do get the Open In box to appear, try closing the mail app and reboot your iPad and then try again.
Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the Mail app and then swipe "up" on the app preview thumbnail to close it.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
If it worked yesterday, I don't think that your iBooks app not being up to date is the problem.
