The OZ Communications IM software will not work until T-Mobile provides a new version of the application to work with the 8700 and 4.2 software. To get around this, I found the link for the 8100 version of the OZ Communications IM software and upgraded. It works, but unfortunately it expects trackball input and I can only activate the first client which is the AIM client because the 8700 can't scroll sideways.
