George Hotz (geohot) is a true genius isn’t he? He has finally managed to successfully unlock iPhone firmware 3.1.2 on 05.11.07 baseband (modem firmware) using his tool dubbed as blacksn0w. blacksn0w will be an integral part of the upcoming version of blackra1n which will be released on 4th November 2009 and it will work on both the iPhone 3G, and iPhone 3GS with 05.11.07 baseband.

The ETA (estimated time of arrival) for blacksn0w comes from the video proof which Hotz posted today that clearly showed iPhone 3.1.2 Firmware, running an unsupported carrier SIM on the new 05.11.07 baseband!

This news should surely be a big sigh of relief for all those of you who have accidently upgraded to the stock iPhone 3.1.2 firmware from iTunes, resulting in a locked iPhone with 05.11.07 baseband.

Stay tuned as we’ll be posting complete step-by-step unlocking instructions as soon as the new version of blackra1n with blacksn0w is out on 4th November.

UPDATE 1: blackra1n RC3 with blacksn0w is now available. Follow the complete step-by-step guide here to jailbreak, and here to unlock iPhone 3.1.2 firmware with 05.11.07 baseband.
