Jeff is never without his cell phone. It's become a part of his identity as it helps him to maintain his persona of being cool and detached from everyone else. He is seen constantly texting, updating his social networks, or more often than not, just playing a game on it in various episodes. Although in the pilot, Britta mentions that Jeff has an iPhone ("Aren't you the guy who sits in class playing Bejeweled on your iPhone?"), his phone is clearly a BlackBerry manufactured by RIM.
|In the Pilot episode, Jeff tries to get Abed to leave him and Britta alone in the study room by sending him a text. He later gets a text himself from Ian asking him to meet with him on the football field. In "Social Psychology", Jeff secretly uses his cell phone to take a photo of a poem that Vaughn had written for Britta. "Home Economics" shows Jeff arguing on his phone with someone he's trying to sell his collection of Spider-Man comics to. In "Debate 109", Jeff leaves his phone behind in the study room after he experiences some sexual tension with Annie. In "Environmental Science", Jeff is on his cell phone when the group nominates him to talk to Chang. In "The Politics of Human Sexuality", Britta chides Jeff for his contact info which lists women he's slept with by their attributes instead of their names. In "Comparative Religion" Jeff takes care to remove a few valuables including his phone before his fight with Mike. The Dean tricks Jeff into showing up to the Greendale Gazette Journal Mirror by sending him a text about free Sephora samples. Britta sends Jeff a drunk dial message laced with B.C.I in the episode "Communication Studies". In "Beginner Pottery", Jeff is playing with his cell phone instead of participating in class.
Even after Jeff is "zombified' in "Epidemiology", he is seen still playing with his phone. After he and the rest of the students are cured by Troy's efforts, he pauses for a second before he resumes playing with his phone. In "Cooperative Calligraphy" he pretends to contact "Gwynnifer" to tell her he's doing a bottle episode and throws the phone down onto the study table. In "Early 21st Century Romanticism", Jeff has a fight with the study group but later realizes he was wrong and apologizes via a text message he sends out to everyone:
"It might not shock you guys to find out the real reason we had a fight today. It wasn't about the Bare Naked Ladies although I do have some unresolved issues there. Caring about a person can be scary. Caring about six people can be a horrifying, embarrassing nightmare at least for me. But if I can't say it today, when can I say it? I love you guys."
In "Critical Film Studies", Jeff uses the phone to coordinate Abed's surprise party at a diner with Britta while he meets Abed at a fancy restaurant. After becoming engrossed with a conversation with Abed, he ignores Britta when she repeatedly tries to contact him on his phone and ultimately throws it in a glass of water to get it to stop ringing. In the season finale "For A Few Paintballs More", Jeff is playing on his phone and ignoring Troy who is trying to rally the Greendale students.
|In "Biology 101", Jeff is expelled from class for interrupting Professor Kane's lecture when his cell phone constantly goes off. When Jeff asks Professor Kane if he can return to class, Kane only agrees if he gives up his cell phone. He says it's a symbol of his pretentious nature and a way for Jeff to keep his distance from other people. He describes Jeff as someone who keeps his walls up and won't let a single blade of grass in. When Jeff is accidentally sprayed with monkey gas, he experiences a hallucination]] where he is eating his phone. Later, Jeff realizes Kane was right and sends him a gift: his cell phone in a potted plant penetrated by a single blade of grass. Kane then kicks out Star-Burns, freeing up a spot in class for Jeff. In "Competitive Ecology", when the study group starts arguing over who gets to be paired off as lab partners, Annie catches Jeff texting on his cell phone. She wonders who he could be possibly texting, seeing as everyone he knows is in the study room. In "Studies in Modern Movement" Britta calls Jeff to see if he's really too sick to help Annie move into Troy and Abed's apartment. With the assistance of a store clerk at the clothing store he is shopping at, Jeff convinces Britta over his phone that he is in the hospital. In "Urban Matrimony and the Sandwich Arts", Annie tells Jeff to look inside his heart in order to find the right words for a toast he's supposed to give at Shirley and Andre's wedding. Jeff looks at his heart, and images can be seen flashing by, one of which is his cell phone.
In an emotional speech to his estranged father, Jeff admits that he spends time composing texts on his cell phone to no one just to avoid having to interact with other people ("Cooperative Escapism in Familial Relations").
