Facebook has replaced its old fairly useless iPhone software with a fully functioning application.

The new Facebook application lets you do pretty much anything you can do on a regular computer. Some key features added include friend requests, notifications, people search, photo tagging/captioning, full News/Mini Feeds, message attachments, and inbox search. It replaces the elderly application that just let you read your news feeds. 

Most users are wondering what took Facebook so long to get its application onto the iPhone in any meaningful way.  It seems likely that Facebook developers were waiting until the second generation of the Website was bedded down before embarking on any more ambitious projects.
