i'm re-uploading 21870 1.5....the supposed MMS fix was using an older version of HTC Messaging, I went back to the latest version I was using b4, enter the below settings in the MMS server, and can still receive MMS in HTC client, but still not sending.
added autotimezone fix
Code:
Server Name - SprintMMSC
Port - 80
Server address: http://mms.sprintpcs.com
WAP - none
Connect via - My ISP (doesnt stick, keeps changing back to "data connection", but technically, data conn & my isp are the same, I think)
