Its definately a good solution compared to getting the
WP Touch pro plugin and tweaking it to get the ads with the thumbnails to be listed, BUT its not bug free either:
The Google Map bug: looking at that link you posted, just clik on the Open dialog link in the menu that points to
http://entalpia.info/hello-world/ and you'll see what I mean, this is a Blog post entry under the category "Noticias" (We do see those which is fine), on the mobile version, a Google map is displayed, which has no business being there.
The search option is sketchy, sometimes it wont even return a very common tag or keyword on the site.
The custom fields: If I delete a custom field within a form because its no longer needed, it remains visible on the Mobile version, I even saw custom fields dating back from the initial deployment of the site.
The plugin is worth it for the price, not gonna argue that, but needs some tweaking, considering that we can only download 4 updates from the day of purchase.
