The MMSC settings are greyed out on my Hero, as per the title I've just moved to Sense Hero 2.1 from Stickman. This ROM was derived from a Sprint 2.1 ROM so I suppose that's why the current settings are for Sprint. I'm on O2 UK, I have all the settings waiting to be put in, but it appears to be fixed/hardcoded. So it tries to connect to the Sprint MMSC. Does anyone have a tip on how to enable modification of this / maybe there's a settings file I don't know about which could be edited on the CLI?
