works great!!
bring on the unlock
dont works my
try it a gain a few times… their server must have been *VERY* slammed, cuz it took me a few times to get jailbroke.
Not as smooth of an experience as I had with 3.1.3 tho… seems a lot of stuff isn't working with 4.0.1. Still has important stuff tho.
I have tried it and its a bingo!!!
How long does it take?
Not More than 10 Mins
work great for my 3gs 16g
keep getting Oops… File received was invalid.
Me too…:(
Mine says the same message. Did you fin a solution?
it wont slide across
That happened to me. Try enabling JavaScript by going to Settings>>Safari>>Javascript where you can toggle the on/off switch.
TY… ive been trying for days now.
This is a great news to get the best out of your iphone, thanks for sharing, I'd better wait for the iphone 4.1 and see.

Tried to do it on my 16GB iPhone 4 4.0.1 and my 32GB iPad 3.2.1 and it wont work. But I will keep trying….
hey all ran the jailbreak ….. hhmm terminal dnt wrk at all ? and cydia keeps coming up with errors language GB and some others ?? and apps installed via instalous dnt show any help peeps cheers
can ant one help with this plz tar very much
you are having problems because these apps havent been optimized for os4 yet since the jailbreak is new. Just wait, there will likely be updates soon.
Cheer pal thought it my phone , so the apps I have downloaded tht won’t and terminal etc will just need to up date when released ? Cheers Lenny
Worked like a charm! Finally I have Cydia back, yeah!
For those who are hoping to do this on their iPod Touch 2G — please don't. It will only make your OS slower. The best platform there is is still the 3.1.3.
I have upgraded my iPod Touch 2G to iOS 4 and I was disappointed. I upgraded it to iOS 4.1 and the feeling is still the same.
Is there a way to downgrade from 4.0? So far I've found nothing that actually lets me. I have an iPod Touch 2G MC.
You have to go into DFU mode, aside from that there is no easy way to downgrade.
smoothly on my 3gs!
Works on my iPod 1st gen
iPod touch 1st gen, I mean.
Works greattttttttttttttttttttttttt!!!!!!!!

Couldn't run jailbreak connected to my PC but it worked fine over wifi. Well done.

I am trying to jailbreak my Iphone 4 ios 4.0.1 but ain t getting nowhere. I do get to the site jailbreak.com and once I slide to jailbreak I get " oops… file received was invalid." and I get the options quit or retry. When I choose the retry button safari didn´t want to work anymore so I had to Reset to factory. Do someone know that the problem might be?
Not sure if you got it to work or not by now… what I did when I got this was turn the phone off and on and everything was alright again. Hope that helps

It hasn\’t been released. Stay away from those who claim it. The legitimate resource is greenpois0n.com
i need and an advice about an issue, i want to buy an iphone 4G and the seller told me that the baseband is 05.14.02 is this true or false? cause as far as i know that this baseband comes on 3G/3GS modules. if this is true is it possible to unlock it or have to wait the 4.2 firmware release.
