Have you ever seen all popular hackers enjoying a party? No, right?
Take a close look at the following picture -
The jailbreak and unlock tool developers from both iPhone Dev team and Chronic Dev team were present today at widely popular DEFCON conference. And, as you can see in the picture, Saurik, Josh Hill, GeoHot, Bile, Justin Williams and other hackers apparently had a great time together during a private party.
As far as the future jailbreak is concerned, you will have to wait for iOS 5 release. The hackers have already said that they are not going to release any untethered tool for iOS 4.3.5 or any other iOS update. Apple will soon release iOS 5 firmware for iDevice users, so be patient!
