I know this is kind late to bring it up, but I still have the mute/unmute issue with both my own and a family member's Vibrant running ExROM. Just to mention it, activating and deactivating speakerphone also works.
Also, I can't send or recieve a picture message through the Messaging app. Any idea on if these could be possibly fixed?
Either that or I'll just wait for JB to be released for the Vibrant
Okay so... your mms info maybe broken not sure...hs from WAS promising... I wiped it and put ICZen on both vibrants and oh my god... there isn't any point to use any other mod than ICZen.... its simply amazing with not one found bug yet other than Facebook force closing at times which is probably a Failbook problem and not a rom problem
