Back then however, Geohot had posted the following disclaimer:
"Warning 3g and 3gs unlockers, do not upgrade to 3.1.2 using iTunes if you want to keep your unlock. Baseband cannot be downgraded. Check out the dev team's offerings. Also blackra1n doesn't hacktivate"
If you are one of those looking for a method to unlock basebad 05.11.07 that was bundled from iPhone OS 3.1 onwards, then there is now reason to cheer. Geohot has revealed yet another impending update called Blacksn0w, that will enable iPhone users who have upgraded (in many cases accidentally) to baseband 05.11.07 to unlock of their iPhones and thus work over any GSM network.
Blacksn0w will be available for iPhone users from November 4 and like the previous updates, this one shall also be free. Also, hactivation shall be made available this time around.
Here is a preview video of Blacksn0w posted by Geohot
We'll let you know as soon as BlackSn0w is available so stay tuned.
