I just got an unlocked bell atrix 4g. I'm with rogers, and I am on a messaging plan which allows me incoming/ outgoing mms. I have received 2 mms on my atrix and cannot get the picture to download. I've tried to download with and without the wifi on.............am I missing something here?? What do I need to do to get the pic to open??I'm also a new "smartphone" user. Thanks in advance!!!!
