When I opened ESPN for the first time it told me there was an update and took me to the marketplace to update the app.
As for Drive, it was there when I setup my 900 at around 7:30 PM west coast US time. Open marketplace and choose Nokia Collection, it is in there, just scroll through the apps. There is also Nokia maps, as well.
Skype may not be findable because it is supposed to be in Beta still, so it is hidden for the most part. The link below will open up a web browser page from the marketplace which will send you a link to your phone through a MMS. It may take a few minutes before you get the message.
