Thanks alot. I am switching from my BB to the Incredible so I have no clue about any of this. So to make a call or send a text through GV do you just go to the app or is it integrated somehow into the regular messaging service?
Calls
You can configure the app to always use Google Voice or ask each time you call or only using it for International calls. I have mine set to always ask. So, I go to the "people" app, search for a contact and click on the phone number to call as normal. I get a pop up to say call via Google Voice (ie, they sees my GV number) or call using my cell phone number (ie, they see my cell number).
Note, when I use GV to call, it actually dials another phone number. Mine is a 615 area code. But, the person you are calling does see your GV number.
SMS
I use the GV app exclusively for text. However, you can use the stock messaging app, but be careful. If someone sends you a text to your GV number your stock messaging app receives it from a 406 number. The first part of the message is the contacts name. I used to save that 406 number to my contacts. When I would initiate a text, I would send it to the 406 number. The person sees it as coming from my GV number. This always works with calling (ie call their 406 number and to them, it looks like your GV number). If you don't want to use the GV app, you can always just use the 406 number. The only draw back I see is to get the person's 406 number, they have to ext you first. So if the person only has a land line, I don't think this method would work.
The way I use it now, I only use the GV app the send / receive texts. Since texts are now push, I get them as soon as they appear on the GV webpage. To call, I always have GV ask me what number to use. With my setup, I unchecked "forward SMS" to my cell phone in GV (via settings on their webpage). Otherwise I was getting double notifications (one via the GV app and one via the stock messaging app) when someone sent me a text.
Hope some of that made sense.....
Edit: where in TN are you? I am just south of Memphis in MS.
