Adding other features - if you have access to wi-fi/edge and have jailbroken your iphone, use the installer.app to get access to a huge list of programs to install. Some of the most useful ones on my phone -
- Books.app - ebook reader for the iphone
- docs - to read a variety of docs stored on your iphone.
- Bossprefs - to manage all your preferences from one screen.
