We are now allowed cell phones with cameras also. However, iPhones are still not on the approved device list (even though our telephony provider is AT&T) because of the requirement of using iTunes with it.
I doubt any device capable of recording or transmitting will ever be allowed in our closed areas. Pretty much the only things we are allowed to take into our areas are CD players (with only factory stamped CDs) and pagers. MP3 players aren't allowed because of the ability to store information on them.
