The application dock has now been ported to 2.0 by Nate Tru. You open it by swiping the bottom of your screen on your iPod and it opens the dock application no matter which application you are currently running.

Now when you open Dock, you will get 5 different categories: Media, Phone, Uncategorized, Utilities, and Work. Most applications by default are in Uncategorized, but default applications are categorized. You can move around applications in the “Dock Prefs” application.
One new feature I do love, is the ability to call any of my contacts with the “Speed Dial” switch turned on in Dock Prefs. Speed Dial will show up next to Uncategorized and you can call any of your contacts.
Overall, really great update, and a welcome addition to my iPhone.”
You can get it of Cydia.
