GeoHot kept his promise like always and he released Blacksn0w, the free unlock for iPhone 3G and iPhone 3GS. That’s not all as the iPhone hacker also updated the iPhone jailbreak thanks to Blackra1n RC3 which is available for download at Blackra1n.com for both Windows and Mac OS X. Blackra1n RC3 and Blacksn0w provide unlock, hacktivation, 15 seconds faster, and Tiger + PPC support, and if you didn’t installed them already, then you should do it because now you can unlock the 05.11.07 baseband for the iPhones.

If you’re using Cydia instead of Icy then run the app, and then add Blackra1n.com as repo, however, this works only if you have iPhone OS 3.1 or bigger and baseband 05.11.07. Some users reported that they are experiencing issues with WiFi, and if that happens to you, then GeoHot recommends you to Reset Network Settings.

Blacksn0w will also enable tethering on your iPhone so you should head over to this link where you can download the MobileConfig file for your specific carrier. Now that you unlocked and jailbroke your iPhone to enable tethering, just watch out how much bandwidth you use.
