Google Search for iPhone has gotten a complete overhaul that makes the app much cleaner, speedier and a bit user-friendlier, if you will.
The updated app, complete with the day's Google Doodle, now automatically fills the screen in both portrait and landscape orientations with search results. You scroll down, and the controls are hidden. You scroll up to reveal them again.
Across the bottom of the screen, you find the categories of search areas including images, videos, news and blogs. This carousel also disappears as you begin to scroll through results. A nice intuitive touch -- if you're looking at results, you don't need the other navigation options.
And, in a bit of a nod to the multitouch gestures of the iPad, Google Search webpage results can be swept away to return to the results page with a quick right-to-left flick of the finger.
