I am having the same problem with my friend who has an Alltel Curve. She cannot receive my pic messages but gets my regular txt's fine. It just started happening as she received my Curve messages fine on Saturday but when I switched to the Tour she could no longer receive them. I do not get back an error, it shows the message went through. I was thinking maybe the file size is too large at full 3.2mp. Other than that I am not sure what the issue is.
