the link goes to the firmware I called <SUPERMARS>
http://moto.it168.com/viewthread.php?tid=361942&extra=&page=1#1 -- the flash firmware
#4 -- development package, and simple HOWTO document
the first fully unlocked E2 firmware that user can modify anything directly.
(seems there're similar firmwares for A1200, E680, A780)
you can replace AMCSL.TTF but no need `mount --bind' to change the font
you can simply delete any original pics and ringtone comes from the firmware
you can edit the configfiles even there're in /usr
