The TUAW bloggers will be passing through the chat during the afternoon as everyone has a chance to download and install the new software. Looking forward to hearing how it goes for everyone!
UPDATE: Yes, iPhone OS 3.0 is here and should be available via iTunes. Read more here. We're still covering installs and reports below.
Another update: We are moderating comments, so if yours don't appear, we love you, but we're getting about 200 comments a minute and there's only so much bandwidth. Please be patient.
