Picasa – Google’s picture browsing, tagging, sorting, viewing, uploading, sharing, free software – has been redesigned for the iPhone interface. Google has also introduced an iPhone-only slideshow feature that automatically flips through a user’s favorite photo albums. iPhone users simply need to navigate to Google’s site (www.google.com) using the Safari browser of the iPhone (and iPod touch) will find a navigation bar that lets them switch between Google services. Really cool. Apple + Google = BFF!
