MMS file is missing

[mburdick]

Has anyone else had this problem when trying to send a pic in an mms? I downloaded 2 background from an app, and I sent one to a friend without a problem. I tried to send the same one to another friend 10 minutes later, but it said "Warning file is missing" It still shows up on my sd card, I can view it and set it as a background, but I can't send it because its apparently "not there" Anyone know what causes this? Thanks
