How do i find a list of authorized devices associated with my iTunes account?

There is no list available from your end.

See Here > http://support.apple.com/kb/HT4627

This does not apply to Computers as they are Not Devices.

Hi,

I am having the same problem. I followed the instructions on http://support.apple.com/kb/HT4627 , but there is no 'Manage Devices' option. I would like to de-associate my old iPhone from my iTunes account.

Thank you.
