when someone responds to a text message i get a copy of the text message in the default messaging system as well as in google voice. what am i doing wrong here? am i missing a setting? (i've attached a screenshot of the settings tab from google.com/voice). is there a setting on the phone i need to change? i am sending text messages from within google voice (on the droid incredible), and whenever someone writes back i get a copy of the same message in the default message program, from 972-676-8649 (which is not the person sending the message), which i'm assuming is a google voice number, that is forwarding a copy of the message.
