Ever get frustrated trying to go back and forth between the SERPs and a website on your phone? Have no fear! Google Instant Previews is now on iOS and Android. While it’s a little slow on my iPhone 3G (then again what isn’t) it still makes life a little easier and saves some time when you’re looking for something specific.

So, how do you use this new addition? Next to search results you’ll now see a magnifying glass – just click that and a new world of instant previews is at your finger tips. In the instant preview you’ll even see mobile versions of sites. While in the end it may be easier to just click a result, go to the site and go straight back to the results page if you don’t find what you need this is still a handy addition.
