    I returned my iPhone 4s to the store today due to some warranty issues.

    I have my 3gs as an backup phone but i cannot send imessage from my iPhone :O

    I can send iMessage from the iPad, but not the 3gs (or not on the 3gs after i changed simcard)

    Anyone have any ideas?

    Try going into the iMessaging settings and turn it off and then on.

    Done, but no diff.

    Tried several times.

    Go to Settings -> General -> Reset -> Reset Network Settings

    iMessage uses a combination of device id and sim card id to make the it unique, resetting the network settings solves this problem (i had the same problem)
