Was it just yesterday/today that it would not receive MMSs? Mine has been pretty much functional, but when I tried it out a few times this morning, I failed in sending and receiving. Gave it about 40 minutes, and it started working again.
Hubby's would not work when we tried it out when his phone was a couple days old, but by the day after, it was fine. I'm thinking it's more of VM issues than phone issues, and is hiccup-y.
