I don't know if anyone else wants to do this but I found a way to use Google Voice with the native SMS app on the Galaxy Nexus. Also, using the native voicemail notification for Google Voice messages. The greatest part is you don't have to have a data connection in order to receive Google Voice TEXT messages when you do this. I've tested it several times with all data (mobile and wifi) turned off and Google Voice text messages still come in, and they are integrated in my native SMS app. Open Google Voice App>Sync and notifications>Receive text messages>SELECT Via the messaging app. While you are on the Sync and notifications screen check "Voicemail Notificaions". If you want it to vibrate or have a special ringtone set it there. Once you have finished, back out one screen. Put a checkmark in "Voicemail Display". I selected "View and play voicemails from the phone call log". Back out and close your Google Voice app. You should be set to go. This may be common knowledge and I'm late the the party. I've asked about how to do this multiple times and have been told by more than one person that it can't be done. Now it can. One last thing. If it doesn't work for you, perhaps it's a tweak that my Galaxy Nexus has that you don't. I'm running AOKP Milestone 5. I have Inverted Google Voice installed and Inverted SMS. I'm not sure if that will make a difference. If you get this to work, let me know. ***EDIT*** One note: While Google Voice text messages come through with or without data using this method, voice messages will not come through until you have a data connection.
