Occasionally I get only the phone number appearing on my caller id, or texts, even though I have that particular number in my contacts. In fact, when I call back or reply I sometimes do see the contact's name.
Also, is there anyway to disable the function that sends a text you are composing when you press the return key? I seem to frequently hit the return key when I'm trying to hit delete. Thus, not only is the text sent before I'm finished composing, it's also sent with the error I was trying to delete!
