Imessage in different window than text messages
Please help!!!
Usually when I write an sms it shows up green and imessages shows up blue, and they both show up chronologically in the same window. I.e. my iphone understands it is from the same person and therefor post both types of messages in the same window. However a month ago or so my boyfriends imessages started showing up in a seperate window from his regular green text messages... Why? We have changed no settings of any sort. Nothining has been altered, and on his iphone both types of texts show up in the same window. My other iphone contacts also show up in the same window with both green an blue texts. How come his dont? His email as such is not a part of his contact details, i did however try adding it to see if that would help make the messages go in the same window but it didnt 😟
He has a iphone 3s i have 4, (not s).
All I want is for the blue and the green messages to live together in perfect harmony within one window... Is that too much to ask???
Please help its driving me crazy for some weird reason :S
iPhone 4, iOS 5.1
