Every time I respring/reboot, I end up with a total of 16 blank icons. I delete them all, respring/reboot, and they're back. What the heck, it's so annoying. I had some blank icons back when I was still tethered. I used the "back up" feature in iTunes to back up my iPod before I untethered and now I can't get these blank icons to go away!!! Is there a settings file somewhere that got restored with the rest of my settings that I can delete to get rid of these freaking blank icons? Thanks!
