The Apple iPad is experiencing a blank update screen for many users. You may see app updates available via the notification flag, but when you visit the update section in the App store, there is no data. This is applicable to all iPad models, although the iPod and iPhone are unaffected by this issue.
The iOS 6 AppStore is a web browser with some local HTML (header and tabs) and content loaded with AJAX, so it might be unresponsive because of Javascript and other assets failing to load. Restores are fruitless and many users have reported that running a factory default does little to solve the problem. Currently the only way to circumvent this issue is to hit the purchased tab and search for updates there.
