ok guys! i finally figured it out!!! me and my friend have been testing it for 2 or 3 days. In order to send an MMS photo to an iphone from a verizon blackberry. in this example it was with a verizon blackberry tour, but im sure it works the same with all verizon blackberrys. There are 2 things you have to do.
go to media box.
click on pictures then picture folders
then make sure you click device memory
any pictures in that folder are able to be sent and received by iPhones.
for some reason you cannot send pictures from the memory card on the verizon blackberry, which is where the camera usually automatically stores it.
if you want to change these settings...
click on the camera button
then blackberry menu button
then options and then go down to store picture and make sure it is set to "in device memory"
once it is clicked on that make sure you save the setting
from then on your pictures will be automatically be saved in the "device memory folder", which is where iPhones are able to receive picture messages from.
hopefully this helps and if you have a different kind of verizon blackberry phone you should be able to do a similiar setting change.
hope this works.
