GeoHotz announced yesterday that he will not be updating the Purplesn0w and purplera1n tools for OS 3.0.1. In fact, he won't be updating them at all. One reason - the DevTeam tools already work. He also mentions that the tools were merely a proof of concept, trying to show better and much more painless jailbreak methods exist than the DevTeam's, which he claims to be "complex"!
I code to make things simple, hacky, and fast. Dev codes to make things proper, slow, and complicated; redsn0w works OOTB. [...] Someone enterprising out there could probably fix it, it's just the kernel patches that are in the wrong place. Exploit and 99% of payload will work fine. But otherwise, purplera1n RIP.
If I do another tool release, it'll hit the ipt3 and ra1nydayless 3GS. Told you I had more holes.
