I have the same issue, I had someone sending me a group of shots and out of the 12 sent I got three that couldnt be retrieved.. Keep trying to "retrieve now" and the message flashes on the screen, data arrows start up and then nothing.. its not your phone its verizon. I had to have then "refresh" my account, meaning removing and adding mms and bunches of test messages before I could get 10 out of 10.... Least you got a new curve out of it,
It Maybe the Network... and have that bomb coverage but crippling built in services like GPS just for 10 bucks a month is wrong!!!
