Today is too lucky for everyone in the iPhone 3G and 3GS community as it's both blacksn0w and blackra1n day. GeoHot released the blacksn0w, the first ever unlock solution for iPhone 3G and 3GS with latest iPhone OS 3.1.2 with baseband 05.11.07, for free. The bonus news is that blacksn0w enables official tethering. Too lucky! Isn't? And you can un-tether from AT&T and Apple's shackle, finally. Also he released blackra1n, a jailbreak for 3.1.2. It has been updated to RC3 with hacktivation support, 15 second speed improvement, Tiger+PPC support, and installation of the latest blackra1n.app
