An inportant question about the iPhone 5 screen!

Question

Not sure if i grasped the concept of the new iPhone 5 screen but from what i understood is that the glass screen n the sensors which detect the touch of ur fingers have been integrated into one screen allowing for a thinner phone, the only problem is that if ur glass were to crack, would that render the touch sensors useless? In the first 4 models if the screen cracked all was well and u only had to worry about the spot of cracked screen n the sensors n screen were fine...now im worried that the sensors and even the screen might b affected...thanx in advance
PS: Im also to understan that the new glass on the phone is superior in resistance than older models but in sure it doesnt make it invinsible

Answer 1

The previous phones were like this
