I recently picked up a Galaxy S4 and used my ip5 sim w/ adapter to test the phone out. After playing with it for a few days, I placed my sim back in my ip5. Prior to switching it out, my iMessage was working just fine however when I started using iMessage again I noticed one of my contacts was not showing the name but actual telephone number. This is only happening with one of my contacts, who is also an iOS user (ip5). All other iMessages are showing their respective names... Any ideas? I made certain the number showing up in iMessage is the same as the contact. Made certain there was no dual contact (name contact + a 2nd stored number only contact) but nothing seems to work... Help?
