I upgraded from a Verizon iPhone 4 to a 4S. Both phones are iOS5. All of my contact information is synchronized through Exchange 2003. After setting up my new 4S, I quickly noticed that names did not show up in calls and text messages. I looked in my contacts to verify they were in fact present. I noticed that the formatting was changed. For example, instead of (XXX) XXX-XXXX; all the numbers were XXXXXXXXXX. If I changed them back to the correct format, the names would show. I checked my contacts in OWA and they are still showing as the proper format. I deleted my exchange sync from the phone and all the contacts. I then set it up again and synchronized my contacts. The same thing happened, the proper number format is gone and no names are shown for calls or text messages. Any ideas?
