I had been searching around and couldn't find a nice looking simple black notification bar. The only one that I could find had a rounded corner bottom bar. So I decided to take the stock ones and edit them in photoshop. This changes the notification bar and the close bar to black. There is also a framwork-res subtheme to change the status bar background to black.
To use this you will need to be rooted, deodexed, and have metamorph installed. Just unzip the file and place the BlackBar folder in the Android Themes folder on your sdcard. Then flash using metamorph. I noticed that it causes the notification bar to start force closing, but after a battery pull or getting lucky and hitting power down between force closes it will work fine. You will need to apply one subtheme at a time.

Edit: I finally learned how to edit .9.png and recompile them so they are correct now.
