Google said today it is introducing a beta version of Google Instant to most iPhone and Android devices in the U.S.

Users can access Google Instant on their iPhone or Android the same way they can on a desktop.

The Google Mobile Blog has more details. “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. If you type [anse], for example, you should see [ansel adams] along with other predictions. 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 says Instant mobile users “will probably notice a big improvement in speed…thanks to a new AJAX and HTML5 implementation for mobile that dynamically updates the page with new results and eliminates the need to load a new page for each query.”

Google says it is working on rolling out mobile Instant in additional countries and languages as well as more device in the coming months.
