title: editable cell in tableview
body: <p>I am trying to implement editable cell in tableview, just like what is available in new contact screen in iphone and ipod
  Right now I have two labels in a cell, one of which will remain same all the time and the other one will be editable. Do I need to change this label to textfield.</p>
