Not a big mod, but a simple theme edit by portalxxl. That is the standart skin with silver theme. 

Motorola ROKR E2

Installation instructions (in the example below you replace the second default skin with this skin):
1. Copy the common.ini and iconres.ezx in the root folder of your memory card
2. Telnet to your Motorola ROKR E2 and type:
# cp /mmc/mmca1/common.ini /ezxlocal/download/mystuff/unKnown/autorun/files/
# cp /mmc/mmca1/iconres.ezx /ezxlocal/download/mystuff/unKnown/autorun/files/
3. You need to perform the following bind commands. You can include them in startup.txt so they will be executed on every phone restart too
# mount --bind /ezxlocal/download/mystuff/unKnown/autorun/files/common.ini
# mount --bind /ezxlocal/download/mystuff/unKnown/autorun/files/iconres.ezx
NOTE: You can replace "default2" with another digit to replace different existing skin
