Not sure if this has been posted before as I could not find anything in the searches but if you rotate the screen in system preferences to 90˚, it sets the resolution to the native 2880x1800. Great for reading and kind of usable if you have a separate keyboard and mouse. Just thought I would share as I did not have to do any hacks or install any software. Handy if you always wanted to see what the native resolution looked like without installing anything on your MBP.
