Facebook has posted a huge preview of the next version of its iPhone application. In coming September, Facebook for iPhone 2.0 will look and feel a lot more real Facebook.

Now with the help of iphone 2.0, you'll be able to search for people outside of your friends, you can also make/approve/ignore friend requests, and you can search your inbox and sent folder, for starters. All these notifications will also arrive in real time while the application is running.
