There is a big change on mine. Holding an icon to go into "jiggle" mode now causes a 10 second or more lock-up until the jiggling starts. Then, to exit jiggle mode, I press home button and the ipod locks up for about 15-20 seconds and then finally goes back to normal. It's horrible. Thankfully this isn't something I do a lot of but when you do need to delete or move something it's AWFUL. I saw someone else mention this problem somewhere but I haven't been able to find the post, or if anyone found a solution.. or if it's just the way it is now.
