How does your iPhone Visual Voicemail work?

It took me a week to get my VISUAL Voicemail working; if you're having issues, don't bother with Apple because the issue isn't at their end -- call AT&T; and be sure that (1) your old voicemail account is closed and (2) your new voicemail is activated. If your phone can't connect to your voicemail, the box hasn't been opened and you'll need tech support at AT&T; to make that happen. If nobody can leave you a message because AT&T; can't find you, this is probably the issue. And don't let AT&T; tell you to go through the iTunes sync again and call back if it doesn't work; they're just trying to hook you up to someone else when you call back ;-)
