RadioAlarm is pretty nicely featured. It has some nice built-in sounds, but the addition of custom MP3s (shuffle up to 10 of them) or SHOUTcast radio is icing on the cake.
Just searched for ChrisL's wallpaper so I could steal it, and found a pretty nice set. They're not for iPhone but they're awesome anyway, and you could always edit them: http://www.studiotwentyeight.com/wallpapers.htm
Do you mind posting the iPhone sized picture of your home screen wallpaper without the folders? I would love to use it for my device!
Ha, we're all gonna have our phones look like Chris'. I found this one today here: http://www.crazythemes.com/veeolay-iphone-shelf-background-wallpaper/3413#more-3413
I already had the snow leopard aurora background, doesn't look so good when you have a full page of folders
