Anyone have better luck than me with this problem? I've encountered this a couple of times when apps need updating: I hit "Update all," then an app or two is too big to update via wi-fi or 3G. So I go to update via iTunes and my computer, but the stinking app doesn't appear to update and the icon hangs in "Loading" status, grayed out. Because it's grayed, there's no way to delete it. I tried a hard restart on the device, but no luck. I called AppleCare, which suggested all the same steps I'd already tried. I ended up having to erase all my content and settings, at their suggestion, which is what I tried to avoid before calling them. Then I end up having to synch interminably long, to load all my stuff back on my device, and having to re-enter passwords on a bunch of apps and email accounts. In two cases, iTunes loaded an apparently new version of the app, but the stinking old version continued to stay in my device. So I'd have a new version of Yahoo Messenger, for instance, and an old one right next to it, except grayed out. With Barnes & Noble's Nook app, I got an error message saying that its resources had changed, so it wouldn't update. But again the stupid icon hung on, grayed out, next to a new version of the app. Ugh.
