Picturemail will not send

[shostetler]

Well, it seems my TP will NOT send any picture mail. I don't know why, I've updated the picturemail cab from Sprint, however none of the picture mails I ever send get sent. They just say they are sending once I click send then sit there sending for a few hours or so then come up saying sending failed. It doesn't matter if the picture file was from on the phone or the storage card. Is there something I'm missing? TIA
