Dear All,
FYI - this is the process that I used to solve the problem.
Go to Settings
Go to iTunes and AppStore settings tab
Turn off Automatic download for Apps using the on/off switch
Exit Settings
Double click the Home Button, and force quit the App Store
Go back into Settings
Go back to the iTunes and AppStore settings tab.
Turn on Automatic download for Apps using the on/off switch
Exit Settings
Turn on the AppStore
Go to the Updates tab
Then, I saw the magic wheel go round, and the Apps that needed updating magically appeared
Hope that the same works for everyone else having problems out there!
