A page created by geohot along with this blog entry: "There is a known exploit in iBoot, on both the old and 3G iPhones. The "the specific date/time is not firm yet" pwnage tool will leverage it to jailbreak all 2.0 software iPhones, 3G and otherwise. Dev team, that date better be soon or I might just have to release yiPhone. The iBoot exploit is yours, use it. You wouldn't want a repeat of ZiPhone now..."
After the deadline came and went, geo declared that it was a joke that some people took a little too seriously.
