Not receiving MMS from just two contacts when iMessage is turned on

[Code19Killer]

I've noticed an issue of not being able to receive picture messages from two of my contacts when iMessage is turned on. They receive mine however I do not get them. All other people in my contacts I get their picture messages just fine. When I cut off iMessage I was able to receive picture messages from those two contacts. Any idea on what is causing this and what a fix might be. I have an iPhone 4S running IOS 5.0.1 and it is jailbroken. Any help would be greatly appreciated. :messages:

Also their names are the only two that have a blue message icon next to their names in my contacts. I have other friends that have ios 5 and iMessage and I do not see this icon. These are also the only two contacts I have sent a group message to. Not sure if that helps.
