I was talking with a friend who has an ipad today via imessage, both of us using ios 5 GM, and before i talked to him I did *3282# to get my data and text usage. We had a conversation and a few min after it was done I did the code again and my sms usage went up by 19 sms. I then counted the messages and in total there were 38 messages between us. I then counted his messages to me and there were 19 in total! I know we were both on imessage b/c he was on an Ipad, and my texts were in blue and had the delivered and read receipts. Is it possible the carriers will ID imessages as texts?
