Something's coming... Since having 100,000 people download a software update is just about as exciting as can be, we're opening up a liveblog in the 2nd half of this post to let you ask questions, share observations and generally get your 3.0 on.
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.
