iOS app - which account?

[network23]

How do you find out which account you purchased an iOS app under?

I have (unfortunately) used several accounts to purchase apps. Now I am trying to sync one to a new iPhone and iTunes is telling me the phone is not authorized to run it, but doesn't tell me which account I need to authorize.

Surely there must be an easy way to find out. It may have been from an account I don't use anymore, so might not remember the email address.

Thanks!

In itunes, Get Info on the application and it'll list the account it's associated with.
