In the middle of the night last night geohot released his jailbreaking tool blackra1n.  It is will jailbreak the iphone2g/3g/3gs and ipt1g/2g/3g.  The ipt3g jailbreak is tethered so you have to run blackra1n everytime you need to boot it.  From what I have read so far it seems that the ipt3g 8gb model doesn’t work.  If you are on a iphone3g/3gs and need to use ultrasn0w then don’t upgrade to 3.1.2 because you will lose you unlock forever. Here is where you can download it from: http://blackra1n.com/.

Recently in his blog, Geohot stated that he wouldn’t fix purplera1n to work with fw 3.0.1.

via his blog:

Full article here!

“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. It was really more proof of concept to show whats possible; same thing with purplesn0w.”

“If I do another tool release, it’ll hit the ipt3 and ra1nydayless 3GS. Told you I had more holes.”

So possibly in the near future, he’ll have it done again. Until then RIP purplera1n!

Not yet confirmed about purplesn0w
