Today was wasted by updates:
- 2 Mac to 10.7.2: took time but worked fine
- iPhone 4 (#1): took quite some time but worked fine
- iPad 2: worked the second time
- iPhone 4 (#2): failed many times ( error 3014 I think, server error at Apple as I understand). At some point the phone was void of anything. Restoring it brought it right back to iOS5 :-).
