iPhone or iPad App Store list of updates aren't visible. Screen is blank. Can't install updates.

Sometimes when I launch the App Store app on my iPhone 4 with iOS 5.0.1, I'll get the little red indicator showing that there are updates available for my apps on the Updates tab but when I go to that tab, the screen is blank. It doesn't show the updates.

I haven't found a really good fix yet but for a workaround, I just hit the home button to close the Apps Store app and then double-click the home button to pull up the task bar that shows the currently running apps.

You should see App Store sitting there since you just opened it. Press and hold on the icon for App Store. It will start to jiggle and you'll see a red circle with a minus sign.  Click on the red circle. This will kill the App Store app.  Now hit home again to stop the jiggling. Hit home one more time to return to the regular screen.  Now launch the App Store app and you should see your available updates and should be able to install them.
