I have an iphone 4s and a question. I am sure the reason it is not answered is because I am stupid. I had all my contacts numbers stored as ten digit numbers. Their names showed up when we texted one another but when they call me their names would not show up, just their phone number. I tried adding a one before the area code for my contacts and now I am having the opposite problem. No names for texts but names in the caller ID on calls. What did I do wrong? Any help is appreciated!!!
