Used as an injection vector for the current iPhone 3G and iPhone 3GS unlock payloads‭ - ‬ultrasn0w 0.93‭. ‬Currently available in all baseband versions until 05.13.04‭.‬ ‭



There is a stack overflow in the AT+XAPP‭="..." ‬command‭, ‬which allows unsigned code execution on the X-Gold 608


applying a string of more than 52‭ ‬characters will trigger the overflow ‭


The exploit was used by iPhone Dev Team in Ultrasn0w 0.93‭ which is able to unlock 4.26.08‭, ‬5.11.07‭, ‬5.12.01‭ ‬and 5.13.04‭ ‬BB firmwares
