Your verification sucks big time! You never sent text messages and I'm locked out of my invite as you have a limit of 3. I signed up with my Google Voice and now I'm in some queue of 150K suckers. How can you design this so poorly? I understand text messages cost you pennies, but you can only turn away early adopters this way, because who else cares about your service at this point? Also, when I switch to my SMS app to get the code and switch back to your app, you're return me to the phone number entry screen and waste another text message. How can I receive I text message from you, when you're in full-screen mode (without any reason, by the way) without switching to my SMS app to see the code?! And why does it need to be a 6-digit number, really? And because of your fancy input, I cannot even paste! This is some poor UX, guys, no offense, but it's like people who never touched this app coded it!
