The App Store is messed up right now. Two apps showed up in iTunes as awaiting updates, but when I tried to download them, iTunes threw an error message, probably the same one. One happened to be the Yahoo Search app, so it's not just happening to little developers. I think I'll sit out a day or two and look for confirmation that these issues have been cleared up before I try to download any more apps from the App Store.
