We released this very basic pack a few months ago because we needed them for various projects.
Facebook, Twitter, Apple and Forrst were all done by hand (no live-trace here!) Dribbble was taken from the available guidelines download page here on dribbble.com.
Please download them and feel free to use them any way you'd like (no attributions required, just please dont redistribute them). I think you'll see that these vectors are about as accurate as they get. The colors are also the official brand colors and you can use them simply by turning off the layer styles.
A new update is coming this week!
