Yup. Mobile devices appear to use a "mobile" Google search platform. You'll see differences between results. I can only guess that maybe the mobile search results use a central or limited number of data centers to pull SERP results from? What I do is use the "standard" search platform and then it shows the same on my itouch as PC for SERPs.
I have found with my research that whatever the ipad/iphone says in the mobile site is normally more up to date then the actual SERPS on your pc. trust me if you see your higher on your iphone or phone etc then check back the next day or so on your pc and it will be the same
