I have found a lot of threads How do I change the google account associated with the android market account on my Droid? Change default Google account [SOLVED] - this one did not work for me Remove/change main google account Is it possible to change your linked gmail account or do you have to do a phone reset - I don't have "Google Apps" in the settings. I really don't want to do a factory reset. I also found RemoveAccGoogle Desire.rar - but I don't know if this will really work. Thanks!
