All I want from the iPhone is Shazam, EverNote and Wordpress. Pandora would be nice because I don't like Slacker as much but Slacker is okay.
The iPhone is very limited by Apple's limitations. Jailbreaking frees up the iPhone. Listening to Pandora while browsing in Safari with Fring also open is great. But even with jailbreaking there are still some limitations such as e-mail and copy and paste.
