UPDATE: I will go ahead post this update but since nobody replied complaining of the same problem or offering a solution, I'm assuming it's just not an issue for anyone here, but maybe someone will stumble across it and be helped. Apparently very few people here must send/receive address book attachments. So far, I have had 3 (maybe more who haven't called me complaining yet) of my 20 users (all TMobile 7100t 188.8.131.52 on BES) come to me with this same problem of not being able to view address book attachments sent from one BB to another. Others with that same software seem to have no problem.
THE FIX: An upgrade to 184.108.40.206 fixed the problem. Whether or not the issue is directly related to the .32 software version, I do not know but the upgrade fixed it. Maybe reinstalling the same version would have fixed it as well, who knows.
