The holy grail of Google Voice with those of us who have dumped AT&T data on our phones is getting it to work as a Voip service. Well I just happen to have a Gizmo account so now I've got a phone that can dial out (not free

) and show my Google Voice number!
Some feedback on the Softphone app:
Good
* very polished technically, lots of well though out options and nice visual favorites
* call recording - wow
* lots of options and I can use multiple services
Not so Good
* another slightly more expensive version has push for VMail. I would of bought it if I knew that but it's not clear anywhere

now I have to buy the other version .......
* Push / Delay - someone calls me and I have to accept the push notification then there appears to be a significant delay between the program launching and accepting the call - this might be a deal breaker on my little iPhone 3G unlocked on IOS4.1, perhaps she it too slow.
*Push - what phone rings. I realize that this is a apple push thing but if the last device I used the product on was say my iPhone and now I running out the door with my iPad without iPhone and the phone rings, push is going to iphone
I don't really want to knock the product here, this phone is leaps and bounds better than other softphones (whistle but whistle is free!!) and also Billion dollar Skype that doesn't even have push yet!!! So if someone could explain why there is a significant delay when someone is calling me with goodvoice and explain workaround for the push that would be great. I'm assuming google voice is not a real voip number / provide and has to do the call back think so that's why there is a delay?
