Not sure if this has been discussed yet, so don't shoot me if it has. So I heard that 3.1 is when AT&T is going to finally support MMS and I also heard that some people are reporting MMS to be working on the 3.1 betas. Last night I decided to just try the usual MMS hack but without switching sim cards and all that. Just installing the hacked carrier settings or whatever. IT WORKED. I was able to send and receive pictures...for a little while. Then today it just stopped working out of nowhere. I have a AT&T family plan with the family messaging plan too. Do you think AT&T just stopped it from working on my phone? Just thought I'd share if anybody else wants to try.
