Or works for me on my iphone 5

I was skeptical to pay $5 bucks after reading all the negative reviews but i saw a glowing review in MacWorld magazine so I figured Id try it out. For me at least, on my iphone 5 with iOS 6.0.1 it works fine. Strangely it even connects quicker than using regular cellular to the same phone numbers. Even my GV texts showed up. I can dial my contacts and really, for me at least, works as expected. I do see room for improvement though. I cant figure out how to delete texts using this app and recent call list shows just the number and not the persons name. But I wanted a tool to make calls using GV as a VoIP utility and it works. Its the killer phone app if you want to make calls on a flight and have wifi only :)
