The Dev Team has released two more videos, essentially proving the 2.0 jailbreak. These videos show an item actually being bought in the AppStore, and then another package being downloaded from Cydia, right onto the iPhone. EDIT: It shows installed packages in Cydia, not one being installed.

Installer has not yet been ported to be functional in 2.0, nor have we got word that Nullriver is going to do so. However, Cydia is functioning beautifully on 2.0, and is supported by all major community sources except iSpazio. Look to be installing and rocking Cydia very soon. In fact, the jailbreak methods include an option to install Cydia directly from the jailbreak screen.
Hurray for APT.
