I'm running this on FF, and it's working swell. Here's a
long thread about getting MMS to work with HTC Messages. Of course, that was for an older version. Everyone pretty much gave up. We could get it to receive, but not send. I ended up changing the setting to receive, and just using old trust sMMS to send.
Here were the settings that made receive work flawlessly, but sends would always fail (it would say it sent successfully, but it would never be received):
Server Name: (Whatever you like (default is SampleMMSC))
IP Address: (blank)
Port Number: 80
Server Address: http ://mms.sprintpcs.com/servlets/mms?X-SPRINT-MDN=8885551234 (replace with your phone #)
Connect Via: Sprint
Send Limit: 1024
WAP Version: None
I just tested, and these settings still receive fine, but can't send. It says it sent successfully, but it really doesn't send.
