Does iPhone have Mac’s kernel?

The iPhone’s kernel and kexts are not identical to the Mac. For example, desktop Macs have kexts for the iSight camera, audio and video hardware, power and thermal management, and serial interfaces. The iPhone has no kext equivalents for any of these, despite having the hardware. The iPhone’s PPP.kext is also missing. For more go to:
