first...dont let the verizon ext rom to run if you want MMS to work with any rom except if you are putting the origional 2.2 rom from verizon back. after installing your new 3.5 rom, you have to make 3 changes...in the registry, add a connection, change the server (all 3 detailed here

use the for any apache kirvin clean and simple, not the sprint one. the new kirvin clean and simple is not the one on the first page...its later on, but i think there may be BT "issues" but try it and see if it works for you. good luck. if you have any questions...ask away. i guarantee it works
