A friend recently sent me a multi-media message (Sprint user, go figure) and I was unable to see it. Ever since, every time I send or receive a txt message, a popup appears in the status bar with the message "Message not received". It then shows "touch to review the message and try again". When I touch it, I'm simply redirected to the "send message" page. I can swipe it off, of course, but again... every time I either send or receive a txt message, this popup reappears. Anybody ever have this and know how to make it go away? Rebooting phone and deleted conversations did nothing to make it go away.
