title: Anyone know whether there is a 5-star rating component on iPhone?
body: <p>In Google groups and some other web sites, there is a 5-star rating component which is pretty neat, such as in this url:

  <p>I am wondering whether there is an existing 5-star rating component in the iPhone environment. Or if there is not, if anyone has clue where to start?</p>
  
  <p>Thanks</p>
