Compounding my rather large and embarrassingly out-of-date queue of apps, I got a "mature content" warning for an app, although Apple never tells you which app might have the inappropriate content. Just a warning that some crazy crap is in that list of 200, so don't go giving your iPhone to the kids -- or something. Worse yet is I'm still getting the -4 error many, many users are complaining about (note: it basically means Apple's servers are getting hammered). So, for now, all my updates are belong to Apple's servers.
What apps are you updating?
