my phone told me there was an update for Facebook today. When I tried to install it, it just put the Facebook app into "waiting" and keeps popping up with a dialog box that says "unable to download app 'Facebook' could not be downloaded at this time." I restored my phone (even in DFU mode) and now it won't let me put the Facebook app on my phone at all. I tried downloading it with iTunes on my mac and it keeps telling me there is an error downloading the artwork and refuses to work that way either. Any ideas?
