Just because your problems aren't resolved doesn't mean the updates are placebos. Stop crying and return the thing, it's probably defective.
I didnt have these problems before 2.0.2, they were there in 2.0 but were helped out a lot by 2.0.1 and now they are back and worse than ever. And what about everyone else in the same boat i am, should we all get together and go to an Apple store to get out iPhones exchanged?
