So I worked on a few iphone themes before and started digging into the system for goodies to modify. I wanted to figure out howto get rid of the background behind each icon. I couldn't find any info on the forum so here it is.

2 files in your current theme folder need to be modified.
Alpha seems to be nokias default blue theme, Beta is the default orange theme, for others they should be the name of theme from what I have seen so far just check the images folder.
/usr/share/themes/beta/images

I'm using the orange theme from nokia so the 2 files I need to change are the following files:

/usr/share/themes/beta/images/ApplicationShortcutAppletPressed.png

/usr/share/themes/beta/images/ApplicationShortcutApplet.png

Just rename these files in term or ssh to .old instead of .png and reboot your phone.
Your icons should be backgroundless ohh and also you can fit more icons on your screen without it looking like a cluttered mess.

More to come.
