I also have problems with the contacts shortcuts. I did use one shortcut before upgrading - to my wife - and after upgrading OTA, it is gone. When trying to re-add it, I can't. Her entry in the phone book is not shown while I search for a contact to add. The menu-item to add a shortcut is not available. It is like it is on the desktop, but invisible and untappable. So I tried adding another contact. Same thing. It is as if I had added it, but I can not see it - and thus not remove it either. Even worse, trying to reboot it was now seemingly dead! Pushing the power button repeatedly or for a long time did not help. Removing the battery did. Having rebooted the contacts are visible for me as well and it is possible to add, move and remove contacts. Time to file a bug, I think....
