These are user-to-user forums, you are not talking to Apple here - I've asked the hosts to remove your email address from your post's title.
Not entirely sure what the problem is that you are having, but if it's that your account is disabled then you might be able to re-enable it via this page : http://appleid.apple.com, then 'reset your password'
If it then works on your computer's iTunes but not your phone then try logging out of your account on the phone by tapping on the id in Settings > Store (Settings > iTunes & App Stores on iOS 6) and then log back in and see if that 'refreshes' the account on it
