I noticed for several weeks that my iPad 2 settings app had a "1" circled near it - which I now know indicated it was ready to upgrade whenever I wished to install the upgrade. Well, several nights ago I was both downloading quite a few podcasts from iTunes, and concurrently updating a lot of apps, when I decided to also go into settings and install the upgrade. Ever since I did that all the app upgrades are now frozen, as well as all the podcasts that were downloading. I've already tried to cold boot (reboot) the iPad a few times, as I synced it, but everything that was in process of updating or downloading is still frozen. How do I remedy this?!! Thanks!!!!
