A few minutes ago the Chronic Dev-Team announced that the greenpois0n jailbreak has an ETA of the 10/10/2010 at 10:10:10 GMT. This is going to be a huge relief to all those who accidentally updated their firmware or got an iPhone 4 after 4.0.2 had been pushed out, like me. The jailbreak will be available at the greenpois0n website.
