You can create a helper like this one using options_for_select

def my_select(object, method, choices, options = {})
  html = ""
  if options[:id]
    html << "<select name=''#{object}[#{method}]''
id=''#{options[:id]}''>"
  else
    html << "<select name=''#{object}[#{method}]''
id=''#{object}_#{method}''>"
  end
  html << options_for_select(choices, options[:selected])
  html << "</select>"
  html
end

And call it from the view
<%= my_select ''telephone'', ''type'',
@telephone_types, :selected =>
''Mobile'' %>

Or if you want a blank option at the top (or display any text) you can 
use the :prompt option.

<%= select(''telephone'', ''type'',
@telephone_types, {:prompt => "Select
Type"}) %>

Hope this helps
