VERY GOOD app + 2 suggestions – GamePhone - Free voice calls and text chat for Game Center Review

Dear developer, This is an AMAZING app. It worked the first time I tried it. (I chatted with a new Game Center friend in Norway!!!) The call quality was very clear and there were no dropouts in sound. However, when I minimised the app, it ended the call! And then I couldn't reconnect with my friend! Some suggestions: 1. Make this app able to run as a background process. It shouldn't be dropping your calls cuz you decide to minimise it to the background. 2. Make the chat feature available to users REGARDLESS of whether or not they're on a call with someone. After I accidentally hung up on my friend in Norway I had a hard time reconnecting with my him. There was no way to tell him what happened cuz the chat feature wasn't available unless he and I were on an active call! 4. Connecting with friends on a call is actually more complicated than it seems. It's not intuitive. I couldn't tell if I was supposed to call through your app or through your app ON GAME CENTER. Please clarify how friends can call each other, and be explitcit. The process isn't clear. 5. Where is your email address? Would you post your email address here and somewhere inside the app itself? I went to your website and saw the contact form. Alright, so I'll write to you there. But I prefer to have a more direct way of contacting developers like via email.
