Google has mobilized their handy Instant Previews feature, which gives user a quick pop-up preview of sites linked in search results. Unlike the desktop version, which shows a preview for one page at a time, the mobile version gives a scrollable slideshow of every page at once. Opening up a few pages in new tabs is easy on the desktop with a fast internet connection, but when browsing the web on 3G, having a coverflow-like overview is very helpful (and saves precious megabytes).
Instant Preview works on iOS 4.0+ and Android 2.2+, and should be available by default on all search results (just tap the magnifying glass next to a link).
