According to this documentation,

Prior to Arduino 1.0.1, it was possible to configure the internal pull-ups in the following manner:
pinMode(pin, INPUT);           // set pin to input
digitalWrite(pin, HIGH);       // turn on pullup resistors

Now, according to the same document linked to above, it says we should be:

setting the pinMode() as INPUT_PULLUP.
