If you set profileID to nil before setting it to a new profileID line, FBProfilePictureView will display the default Facebook profile image while it is selected. This way, at least for now, you will not display the image from the previous cell.
Please note that setting the profile ID to the empty line @ "" will NOT have the same effect as displaying the default Facebook profile picture.
EDIT: I just upgraded to FB SDK 3.7, and the default profile image no longer displays as described above. Instead, when given nil, it does not display the image at all.
