Last night Google rolled out a brand new interface for Google.com built specifically for the iPhone.
When you visit Google.com with your iPhone you get a toolbar at the top of your screen listing:
Home (search box)
More (docs, sms, goog-411, news, photos, blogger, and notebook)
I have tried it out on my iPhone and it works wonderfully, switching between the various web apps (Gmail, Calendar, Reader, etc.) is incredibly fast and seems like the other apps load in the background so when you need them they are already there (most likely an addition because of the slower EDGE network).
I have a feeling that I will end up using this incredibly often since I seem to live inside of the mobile versions of all of the Google apps while using my iPhone.
If you have an iPhone you really need to check this out because it truly is a great looking and very functional interface.
