Why is there a tiny blue speech bubble next to one of my contacts?
Today I went to send a text message to someone and as I was selecting the person from my contact list I noticed that one 1 of my contacts had a tiny blue speech bubble next to his name. I know that the blue speech bubbles when texting mean that you are using iMessage, but I don't know why this little icon appeared next to this contact's name. And why it would show up only next to his name and not next to any others' who have iMessage enabled. Any ideas what this symbol means?
iPhone 4S, iOS 5.0.1, text messaging, iMessage
