I like Dave's answer the best.  It's a nice technique.
Now I have this thing about reducing lines of code for no reason, so
here is a savings of a line or 2:

File.open('phonespec.txt', 'a') do |myfile|

  puts "Welcome to MyAddressbook. Please follow the prompts."
  puts "If you wish to end data entry, you may do so at any time"
  puts "by type the word END into a prompt."

  catch (:done) do
    loop do
      result = []
      ["First name", "Last name", "Phone"].each do |prompt|
        print "\t#{prompt}: "
        result << gets.chop
        throw :done if result[-1] == "END"
      end
      myfile.puts result.join("\t")
    end
  end
end

Of course Dave's is better from a maintenance standpoint (and his also
deals with input EOF), I'm just having fun.
