I tried making the title as descriptive as possible…
What I was wondering was; if it is possible to show a different number of posts on the front page on a mobile/handheld device..
I guess you could do some if else for the query, and user-agent would be involved somehow. but I was wondering if there is some bulletproof solution? so that no browser or mobile/handheld would reach the full version?
You can detect whether or not the user is on a mobile device on your wordpress site with the script at http://detectmobiledevices.mobi. As the article says, simply add this to your themes folder.

If you don’t have a seperate mobile theme this is probably the way you’d want to go.
