With the help of Stevon I've cobbled together a different Safari icon. I still consider it a work in progress, but I've already spent more time on it that I wanted. I need to move on to making a better icon for iFlickr and the Todo list now. So in the meantime, here's something to spice up your Springboard.
FYI, you can upload this to our Summerboard themes folder if you don't want to overwrite your own files. Just upload them to a new theme, or an existing one. The icon needs to be put inside of an Icons folder inside your theme folder. Rename icon.png to Safari.png for it to show up.
Here's the icon:
And a matching Dock:
