Anyone else having trouble using Google Voice? I'm trying to use it on my shiny new iPhone 4s (iOS 5) and it's just not working. Texts are working fine between it and all my family's phones, and my friends' phones, and even AIM's text message service.... but not with Google Voice. I can't seem to receive OR send texts to my google voice number. I was getting 0 error messages, until I tried to text my iphone directly from the google voice web interface, and I got this message: Error: this message was not successfully delivered.
