Ranking in Google Mobile - and Google "Classic"

[stgeorge]

Hi All.

I just started looking at Google Mobile.

My sites rank page 1 for a number of terms but if I try Google Mobile, they don't rank anywhere.

Sites that appear around mine on Google "Classic" still appear on Google Mobile.

Does anyone know of any criteria that is required by a site to appear in Google Mobile?

Thanks

The only clue I've got is Google's patent application, which focuses mostly on classifying which content is practical for mobile devices:

Google Patent Application: "Electronic content classification" [appft1.uspto.gov]

There's a lot here, but they key seems to be discovering programmatically if the content of a url is usable or not.
