Google Instant which was introduced to computer users back in September of 2010 is now on available on any iPhone or iPod Touch running iOS 4 and Andriod 2.2 or later.
In case you aren’t familiar with Google Instant, Google Instant displays results as users’ type, rather than waiting for the user to hit the search button.
Steve Kanefsky an engineer at Google wrote in a blog:
“Google Instant for mobile works best on 3G and Wi-Fi networks, but since the quality of any wireless connection can fluctuate, we’ve made it easy to enable or disable Google Instant without ever leaving the page.”
Below is a video demonstrating how Google Instant works.
