When Tori was about to throw her phone in the bin, and she says "Jam it!", Talking Reggie never spoke and when Tori kicks the bin and leaves, Talking Reggie speaks way too late and it speaks longer. Talking Reggie also failed to repeat certain phrases from Tori in exactly the same way they were spoken too in the final scene.
Just before Tori's phone falls off the counter you can see that her index finger presses the place where you would press Answer on a iPhone.
