Atrix doesn't receive some MMS
This is a very strange problem. My Atrix is being very moody and doesn't receive certain MMS (all picture messages). Sometimes it receives them and sometimes it doesn't. I have tried turning on and off Wifi. I turned off Advanced Task Killer. It doesn't have a pattern either (like not receiving from iPhones or from the same people). A red circle with a black x pops up in my notifications bar and when I open the message, there is a grey download box. When I click download, it says "downloading" for a few seconds and then doesn't download it. HELP!!!
