Help DHD won't receive picture messages from iPhone4

[Bedroom Eyes]

My girlfriend recently got an iPhone4, and I have my new DHD. Sometimes we'll send picture messages to each other, and usually she can receive mine, but about 8/10 times I won't be able to receive picture messages she sends me. I'll turn 3G on and even then, it won't work. It will usually give me a message that says "Content removed because your handset cannot display it."

Any idea as to why this is happening? I'm on Telus and she's on Bell.
