Usually on Tuesdays, you not only get tested on The City's tech treats, but The Hills gadget goodies as well. Sadly, both shows have finished up for the season, but that doesn't mean I can't have some tech trivia fun! The second half of season five of The Hills certainly brought us lots of drama with the return of Kristin Cavallari, alongside many other memorable moments. I've rounded up some tech highlights from the past ten episodes, so let's test you to see if you were able to catch them all! Good luck!
