Removing the vibrator assembly. It's new and... improved?

Vibrator mechanisms seem to be one of those choices like Coke or Pepsi where there is never a clear answer. Apple keeps changing this part's design:

iPhone 4 (counterweight)

iPhone 4S (linear oscillating)

iPhone 5/5s (counterweight)

Based on appearances, we're guessing that Apple went with a linear oscillating design in this rendition of the iPhone.
