Joe Walnes, a software engineer at Google, said that Google has just launched an iPhone-friendly interface of Picasa for the iPhone. Now, whenever you go to Picasa on your iPhone and log in, you get an interface that shows you all of the albums you uploaded to Picasa Web.
If you click on any of the albums in the new interface, you get a full view of your picture with comments from your friends. They also built a slideshow button into the top bar that lets you watch the images scroll by. You also have the option of searching for photos in your album or the albums of others in community photos. Lastly, you have the ability to view your friend's albums through favorites.
