Hmm, how about this?
str.gsub(/\w.*?[.!?](?:\s+|\z)/){|c|c.capitalize}

Of course, this is wrong for example "iPhone is designed by Apple in California."

I think it would be helpful if `String#capitalize` could capitalize _sentences_, and not just the first letter of a string. We could optionally pass a regexp to identify sentence boundaries. If we don't pass this parameter `capitalize` behaves as before.

  s = "hey all! wassup? i am good."

  # current capitalize
  s.capitalize #=> "Hey all! wassup? i am good."

  # new capitalize
  s.capitalize           #=> "Hey all! wassup? i am good."
  s.capitalize(/[?!.] /) #=> "Hey all! Wassup? I am good."

I am not sure what would it take to implement this.
