I tried it and don't like it so far. I tried the option to use google number as sprint number because I paid for it awhile back, I like the number, and I don't want to lose it. I think that google should allow you an option to keep your gv number, even if you make the sprint number the gv number, if you paid for the gv number in the first place. If you paid for it, they shouldn't throw it in the pile to expire in three months.

Fortunately if you pick the same option as I did, the use gv number as your sprint number, you can back out and make them separate again without losing the google number. Nothing happens to the sprint number, as far as I know.

Something that still seems unclear is if doing this integration makes people with mobile to mobile have to use their landline minutes, even if they are talking to someone on a mobile, because they are going through google.

I posted my questions and findings in the epic forum awhile ago. I'm not certain if choosing the google number makes all your calls route from sprint to google then out or what. I don't remember making any calls to see if the lag issue still existed or not. I don't know if there might be a call routing problem sometimes like there is when using separate numbers and making a call but choosing the use google voice to make the call from the gv app. No use in asking the sprint people about this because you will probably get different answers. Also trying to search google help for voice is like the needle in the haystack thing.

Ok, here's some tests I ran and my results. If you can try these yourself and see if you can get different results by trying different things, things I might have missed, please do and post your results.

The first test I changed my google voice account so that my google voice number was my sprint number. After restarting the gv app as instructed, I lost the ability to do some stuff. The choice to use, or not use, google voice to make the call is gone. I wasn't able to call anyone at that time to test if there was lag in the audio or not. I tried sending a text from the stock app to my sprint number and it went through and showed my google voice number as the originating number. The text went to the stock app, but I don't remember if it went to the gv app or not. I sent a text from the stock app to my gv number and the message bounced back to the stock app and gv app. I tried sending a picture from the stock app to my sprint number. It acted like it sent but I didn't receive anything. I tried sending a pic to my gv number and nothing received also. I don't know if it actually went out or not. I didn't have anyone to send a pic to to tell me if they got it or not. I was trying this late at night. I don't know what would have happened if someone called my sprint number if the phone would still ring or not.

I went back into google voice on the computer and changed the settings so that it wasn't integrated anymore. I logged out then back in with the gv app on the phone. The choice of using gv to make the call came back. I sent a text from the stock app to my sprint number and it bounced back like expected. I sent a text from stock to gv app and it bounced to the gv app as expected. I sent a pic from the stock app to the gv number and it went out but never came back as usual. I sent a pic from stock to sprint number and it bounced back.

What I am guessing is that, from my experiences, you can't receive attachments if you make your gv number your sprint number. Like I said, I don't know if the attachments are going out or just acting like they are. When numbers are separate, pics bounce back when sent from then to my sprint number.

Unless someone finds out something different, or google fixes stuff when they make it live, I will be staying with separate numbers and conditional call forwarding and being able to hide behind my google number when calling people I don't want having my real number or I might want to block them some day. There's been word that mms is either in the works or done with google voice, it just hasn't been officially made live or an updated gv app that allows attachments yet.

I will wait and see what happens. Like I said, maybe I missed a setting somewhere? I don't know. Everything looked okay in the settings on the google voice account on the computer.
