To whom it may conern, i recieved an iphone from a friend recently (iphone 5) with a shattered screen. it does not work anymore, and the home button is damaged beyond use as well.. The kernel of ios is the xnu kernel. to learn about what "kernel" means in general, see the wikipedia article.. pre-2.0, it was vulnerable to the ramdisk hack and may still be, but iboot doesn't allow boot-args to be passed anymore. it is mapped to memory at 0x80000000, forcing a 2/2gb address separation, similar to windows 32-bit model.. My iphone 5 is closed when i try to open dfu mod
