CJ's phone is a key symbol in 100 Things to Do Before High School because it is in every episode. It is how CJ introduces the "Thing" that the gang is going to accomplish during that episode. It is a White iPhone 5 that has a light blue case. CJ wakes up to her phone alarm and also texts her friends with it. She also plays music in the hallway for a spontaneous dance party along with a Bluetooth speaker.
