Try Espacenet or Google Patents instead. USPTO has been the worst of the patent search sites for a long time.

Go to http://ep.espacenet.com/ type in "us20080270152" click on the correct number, http://v3.espacenet.com/publicationDetails/biblio?DB=EPODOC&... .

Note that A1 tells you it's a first publication. B patents are granted.

http://www.google.com/patents doesn't appear to have this application yet.
