Good News for iPhone users that new version of Google Mobile App for iPhone was approved and is now available on in the App Store everywhere.
Latest in this version are the redesigned search results display that shows more results at once and, more importantly, opens web pages from the results within the app. This will get you to what you need faster.
For those less utilitarian and more flamboyant, they've exposed visual tweaks settings called "Bells and Whistles" - some of our users had discovered this already in previous versions. You can style your Google Mobile App in any shade: red, taupe, or even heliotrope. If you're on a faster iPhone, like the iPhone 3GS, you may want to try the live waveform setting which turns on, as the name suggests, a moving waveform when you search by voice.
