I went back to midnight rom for the moment, as I really can't live without MMS. A bunch of my friends have iPhones and I get group chats from them which come through as MMS messages (granted not grouped), but I missed out on some get togethers because of it.
I tried setting up GoSMS with some MMS settings I found in the triumph forum, but it still wasn't working, so that's my only issue with the rom. Once that gets fixed I'll be back on MIUI for sure. I miss it already!
