Anyone that missed out on the official upgrade I just got an email that it is back. A quick look shows that the release is the same .297 but the software platform is different .247 instead of .243, they made some change in there for whatever reason it was pulled.
Those that didn't get a chance to turn on Visual Voicemail before AT&T pulled it off their site can turn it on now as it is back to an option according to my buddy that couldn't select it when they pulled it but now can.
