How to get Google's web based apps for the iPhone

Ok, it’s not Android, but it’s still pretty sweet. Google has combined and optimized a bunch of web apps to work on the iPhone. What makes it so great is that there is a menu at the top that links to all the other apps. It also seems to pre-cache your other apps so when search it’s searching images in the background and they are ready right away when you tap images. Here’s a list of the apps: Google search, image search, local search, news, Gmail, Calendar, Reader, GOOG-411, SMS, Picasa Photos, Blogger, Notebook.
