My phone gets bricked if I update it to 7720, the touchscreen stops working and then if I try to use it the phone restarts. Any other version works like a wonder like the 7004, 7392, etc. So I'm waiting for the next version.
I googled it and it says I can find the MMS settings in the EM but it doesn't appear there... even doing the "qwertyuiop" trick...
The only settings that appears in Settings/Cellular is for data connection not for MMS
This is what I get in the EM Menu (after getting a matrix image while loading)
