title: phone number format for iPhone
body: <p>I have to make calls programmatically in my iPhone app.
  I have set of numbers in different countries with different formatting - braces, dots, spaces, "+" sign.</p>
  
  <p>Can I simply remove all of this and left only numbers?</p>
  
  <p>for example:</p>
  
  <blockquote>
    <p>+1-(609) 452-8401 => 16094528401 // usa<br>
    +49(0)89.439      => 49089439    // germany<br>
    +1-(949)586-1250  => 19495861250 // los angeles, usa</p>
  </blockquote>
  
  <p>Will it be correct?</p>
