Continuity: In the episode where Carly's cousins come over, Sam goes upstairs to read a book. When her cousins are gone and Carly goes upstairs, she sees a boy rubbing Sam's feet. In between shots, Sam's right foot goes from facing inwards to being flat.

Continuity: In one episode (I think it is "iPromote Tech Foots"), Sam hires a personal chef, Sonia. In about the middle of the episode, Sonia is making blueberry muffins while Carly, Sam and Freddie are sitting at the table and Spencer is talking to them. Sonia takes the muffins out of the oven and puts her oven mitts down. Next, Spencer starts walking away. Then Sonia is putting down her oven mitts again. There is no way she could pick up and put down her oven mitts that fast.

Continuity: In the episode where Carly turns in her history report, when she's with the paper at home, it has no holes punched in it. When she got back, however, it was 3-hole punched.

Continuity: In the episode "ioweyou", Spencer is talking to the Sunshine girls about stealing his spot. After he gets pushed in the street, when his skateboard goes flying and breaks in two, one half goes offscreen, and one goes under the table. In the next shot both halves are by his feet, but in the next shot they are back in their original positions.

Revealing: In "iWant More Viewers", when the gang is "Messing with Lewbert" and they zoom in on his wart, you can easily see it is just makeup.

Continuity: In some episodes, Lewbert's wart is small or not even there.

Character mistake: In the episode "iHate Sam's Boyfriend", when Spencer is making his claymation movie, he says if his set is messed up, he has to start the whole movie over again. However, Spencer still has all the frames he previously shot, so he just has to shoot that last frame again. But Spencer still shoots the whole thing over again. Also, when he is shooting it again, he doesn't move the figures at all.
