Update: Okay, all systems are go! Updating with pics after the break. We're installing AIM and some other apps on to test -- we'll have photos in just a moment.
Update 2: Looks like our upload of Super Monkey Ball caused iTunes to crash out! We've got the wheel, folks.
Update 3: Alright, we've got it syncing again -- but it's taking forever. Hard to tell if this is due to apps uploading or not. It's like watching paint dry.
Update 4: Our bad -- music was syncing. Applications are up and running smoothly -- take a look at the new batch of pics in the gallery below. Also, the update has been tested on both a jailbroken and non-jailbroken phone and it's working as it should.
We've got more specific info on apps and changes after the break, so take a peak.

iPhone firmware 2.0 is live (plus hands-on)
So right now, it looks like AIM is working when the phone is sleeping, though it doesn't seem to alert you to new messages until you've woken the device up and checked AIM. Then they come at you rapid fire, which is a little unusual. Thus far, we have discovered no way to turn off the sounds in AIM. If you know the sounds, you know how annoying that is.
Push email is kind of working, though it doesn't appear to push changes from webmail to the phone (we can't check MobileMe yet since it isn't live), but Yahoo! Mail works just as badly as it did before.
Google Maps now has 3D buildings, which is a nice change, though little else seems to have been altered.
Most of the applications remain largely unchanged. Take a look at our App Store roundup post to see some more of the interesting downloads available.
