2.0 is supposed to be released today according to Steve Jobs. Apple decided to release everything a day early. This is why we have iTunes 7.7 already.
A few more hours to go and we will all have 2.0 and then we can add the apps to our iPhones.
The above was for people insisting that 2.0 is coming out Friday.
It said on Apple's site that it was coming out tomorrow. (With the instructions for configuring MobileMe on iPhone - I signed up for the trial before it went down).
But I'd LOVE for it to come out right now!
