I can send MMS messages, and receive the text of an MMS sent to me, but I cannot receive pictures. I just get "message receipt failed, try again later." I am using the mms server
http://mms.sprintpcs.com/servlets/mms
because that worked on a previous rom, but before I changed it the problem was at least as bad.
Edit: This is occuring both through HTC messaging and through Windows messaging.
