Easiest way to do this is with FExplorer. Make *ANY* bmp file on your computer (can even be colour). Make sure the pixel size is 97x25 or less. Locate file in FExplorer and do Options|File|Set as operator logo. Now confirm reboot. Now use FExplorer to locate the bmp in c:/system/apps/phone/oplogo, (the name will have changed relative to your network) and rename the extension from bmp to mbm. Now reboot and enjoy your colour operator logo! I've made a Capcom one to go with my super street fighter 2 X wallpaper! Btw, how do you make mbms? Are they just gifs with an mbm extension?
