title: What is an easy way to distribute beta builds?
body: <p>I have an app(an iphone game of about 35MB) that is in the beta testing stage.  It has gotten too big to send as an email attachment and so I need a better way to distribute it.  </p>
  
  <p>I don't have a good website set up so I was thinking about just distributing it with Dropbox, but then it looks like that will mean they all have to sign up for drop box first.</p>
