mbus/fbus cable

what can i do with a mbus/fbus cable ive upgraded to a 3315 and tryed to put a custom start up logo it worked on my old dead phone but it not work on my new cool phone it could be summat to do with logo manager being (CRACKED) im too cheap to buy it. so what else can i do with it. can i make fading leds n crap cos they look coll on the 8310

try going into settings and sellect in f bus, one time my cable would not work, I changed the setting to f bus and it worked fine just makes a differant beeping sound to indicate the logo/ring tone/whatever you sent made it to the phone. I use a cracked version too, so just try diferant settings. Hope this helps some.
