Firmware 3.1.3 Is Upgrading The Baseband To 05.12.01

About an hour ago Apple unexpectedly released a firmware 3.1.3.  With this new release, Apple update the baseband of the iPhone 3G and 3Gs (for the iPhone EDGE is unchanged) thereby blocking the possibility of unlocking these devices with blacksn0w, the hack developed by GeoHot.

Firmware 3.1.3 blocks the usb_control_msg exploit used by GeoHot to unlock the device. Also , we tried every jailbreking tool and none of them are working with the new release.

If anything new pops up , we will keep you updated. Stay tuned…
