Earlier, Cameron tells the Connors that terminators would not recognize John Connor because no one in the future knows what he looks like. But when Vick's chip re-activates and operates John's computer camera, the camera zooms in on John and on Vick's visual screen is printed "Target Acquired John Connor". He should not know what John Connor looks like.
Terminators have the ability to record and remember and mimic human voices. They also have excellent hearing. Therefore, when John shouts Cameron's name in the school corridor as terminator Cromartie is walking away, Cromartie should have been able to hear and recognize John's voice, especially since he has heard John's voice before and John is his prime target for termination.
As John Connor is reinserting Cameron's chip back inside her head, you can clearly see some wisps of hair sliding up her chip indicating that it is actually a reversed shot of taking the chip out of the head. If there is a wisp on the chip on the immerse it would rather go into loops than be stretched like a rubber band as we can see it in this shot.
Bluetooth is misspelled as 'Blue Tooth'.
When everyone goes to the hills of LA to look for the woman, Cameron holds up an actual photograph to match the topography. Why go through all the trouble of printing the picture from the chip when she is able to store the image in her memory just by looking at it? After all, moments ago, we saw Cromartie do this when trying to match the image of John with the guys in the shower.
