Google hopes its revamp (right) offers up a cleaner layout for finding links.

Google released an update to its Google Search app for iPhone today, claiming that the new and improved app is up to 20 percent more responsive than the previous version.

Interestingly, Google has decided that one of its signature features slows down performance and might erode accuracy. Just Talk uses the iPhone's accelerometer to activate voice search when you lift the phone to your ear, and was quite the stir when it first debuted. It's now turned off by default, though you can enable it in the settings and you can still manually launch a voice search by pressing the microphone button in the app.

In addition, Google has jiggered the search results to make them more finger-friendly. Fonts are larger, and you no longer have to precisely tap a link to open the page' you can just hit just the target area. It looks like the concept of "fat fingered" selection has sunk in.

Google Search is free, and it's available in the App Store for devices running iOS 3.0 and above.
