iPhone 3G S Unofficial Blog

iPhone OS hacker GeoHot, the man who brought you the jailbreak tool purplera1n, has released Blackra1n RC3, an updated jailbreak and unlock utility for the Apple iPhone 3GS and iPod Touch.

This version provides true carrier unlocking for iPhone OS 3.1.2 and baseband 05.11.07 by taking advantage of at+xemm crash exploit discovered by ih8sn0w.

The Blackra1n jailbreak process installs a new app, called Sn0w, onto an iPhone. It unlocks your iPhone, making it usable on any GSM carrier network. The blacksn0w unlock is available for free via Cydia by adding the repository http://blackra1n.com in the Manage->Sources panel. More information about the jailbreak can be found on GeoHot’s blog.
