Google Voice + Sprint integration

[josh90265]

So I've been looking into this whole Google and Sprint integration and wanted to see if anyone had the scoop on the matter. First off, I know there are different ways that you can integrate:

1. Get Google Voicemail for your existing mobile number.
-Keep your existing number with your carrier and get the lite version of Google Voice which includes some of the most popular features like online voicemail and voicemail transcriptions.

2. Port your mobile number to Google Voice
-Porting means that you move your number from your carrier to Google Voice. You can then use the full set of Google Voice features without having to change your number.

And finally...
3. Use your Sprint mobile number with Google Voice
Sprint users can now seamlessly use their existing mobile phone number as their Google Voice number, without having to move their number from Sprint.

Number 1, you simply find a G number and use the Android app to access it. Number 2, you have to move things all around as far as canceling sprint service, porting the original number to Google, getting a NEW sprint number, and finally using your original number as the GV number.

I was curious about the last one. And if anyone had tried it, what their opinions were and the ease of use. As well as the matter of disabling GV service so you could just go back to normal sprint service, if need be. I just want to make sure if I add my sprint number to GV that it won't screw up my original sprint service as I am on a family plan, unlimited data, 1500 minutes.

Any information would be greatly appreciated.
Thanks
