yep, i experienced it yesterday with my facebook app.. I uninstalled it and immediately tried reinstalling but app world said device profile not supported. After half an hour so I tried to reinstall again, and it worked...
I.have the same problem but with different version numbers. I now have to blanks in installed and one duplicate in uninstalled. I cannot delete blank apps -> not supported by your current device profile. i had this a week ago after an upgrade. Then I deleted the new file and then the blanks also disappeared. Reinstalled upgrade and all was normal again.
This time upgrade was for Air browser and i now have the blanks and can find no way to remove.
