Apple has launched a directory of applications specifically made for or working with the iPhone and the iPod touch.
It features web-based applications and widgets only such as FaceBook, Big Bang Sudoku UltraLingua Mobile, Digg iPhone Application and SmugMug.
It is available on Apple's web site through the following URL:
http://www.apple.com/webapps [1]
The company was recently rumoured [2] to be preparing a true development kit for standard iPhone applications which run directly on the system instead of running through the web on Safari.
