I know way back in the CM 7 days, I had a bunch of issues with Bluegrass Cellular and MMS when I used CM. I fixed this by updating my APNs and flashing a modified Misc.img. I still have this Misc.img from my HTC Desire CDMA phone, but now I have a HTC Deluxe. Is it okay to flash that same file and see if it fixes the MMS or does anyone else have a better idea?
