This is now available again from AT&T, but there is a change...
EDIT: Hmm...they changed the package...the new info:

Original package:

So, the software platform has been updated? Interesting...I was wondering why I was prompted with an upgrade when I sync'ed the other day. Anybody know what changes if you only upgrade the platform? Anybody care to be the guinea pig?
