Creating Multiple iPhone encrypted backups Is it possible to create multiple encrypted backups with different passwords in different iTunes? 

For example, if I create an encrypted backup in iTunes 1 with password 'abc' and then plug the device into into iTunes 2 on a different computer and try to create another encrypted backup. Will I be able to set password 'xyz'? 

From then on, when I return to iTunes 1 will the backup password on that iTunes be 'abc' or 'xyz'?
You can sync (and backup) your iDevice with one computer only, so the problem of assigning different passwords doesn't come up at all.
