It appears that GeoHot has found a jailbreak for all iPhones and iPod touches running OS 3.1. He made the announcement on his blog with a post entitled, “Meet the Family”.
And prepare to meet the program that will jailbreak them all.
Good news!
Now everyone will know that the DevTeam and GeoHot are no longer in good terms and in fact shortly after the release of Redsn0w 0.8, the tool to run the jailbreak of Firmawre 3.0, there were many discussions on Twitter between GeoHot and copumpkin, one of the DevTeam members.
GeoHot complained that redsn0w uses the same “hole” and the same exploit to run the iPhone 3GS Jailbreak, copumpkin said that the flaw was the same but the exploit was completely different and created entirely by them. Not trusting, GeoHot asked repeatedly Hash codes (the identity) for the files needed to run the exploit and said that it had not been a good idea to release two programs that use the same “hole” (stealing?).
GeoHot also said, that redsn0w has problems (which is true, some users have reported problems) and so he plans to release a new better version of Purplera1n. It will probably will also unlock the iPhone.
Redsn0w, jailbreak tool from DevTeam, is updated to version 0.8. This is for firmware 3.0 and now it supports:
You should use it instead of purplera1n tool to jailbreak and activate iPhones and iPods.
