Google today brought Google Instant to most iPhone and Android devices in the U.S.

Google Instant makes search faster by displaying not just predictions but actual search results as you type. In September Google started working on bringing Google Instant to mobile, and today the company is making a beta version available to iPhone and Android devices in the U.S. To try it out, go to google.com in your phone?s browser and tap the Google Instant "Turn on" link beneath the search box.

Like the desktop version of Google Instant, when you type on your mobile device you?ll see predictions of what you might be searching for. Results for the first prediction appear automatically, and tapping on the other predictions will display those results. Pressing the enter key or the search button skips the predictions and will display results for exactly what you?ve typed.

Google Instant on mobile is also faster when you search thanks to a new AJAX and HTML5 implementation that dynamically updates the page with new results and eliminates the need to load a new page for each query.

Google Instant for mobile works best on 3G and WiFi networks, but since the quality of any wireless connection can fluctuate, Google has made it easy to enable or disable Google Instant without ever leaving the page.

Google Instant for mobile is currently available for Android 2.2 ("Froyo") devices and iPhones and iPods running iOS 4 in the U.S. in English. Google is working to support additional countries and languages and more devices in the coming months.
