So I'm running CM9 4.0.4 ICS Liberty on my HTC Aria. I seem to have an issue where when I get MMS I get no notification because it hasn't downloaded the message. I keep my data off and therefore the message just sits as unread but I don't hear a sound nor will it show in my notification bar. Can I just replace my current MMS apk with a stock version that hopefully will auto download my MMS without me needing to go turn on my data. When I was running stock it was easily done without anything on my part.
