According to the latest blog post by P0sixninja who happens to be a member of Chronic Dev Team, he will be releasing an exploit for iPhone OS 3.1.3 and iPhone OS 3.1.2 which will Jailbreak all iDevices by the end of April. As far as unlock for these iDevices is concerned, you have to wait until Next Generation iPhone 4G is released. He further added that many people think that Greenpois0n is an exploit, infact its not an exploit but toolkit which helps the hackers to discover and exploit new vulnerabilities.
He said although the tools like Redsn0w and blackra1n use same exploits at the backend but still they don't provide enough flexibility nor advanced capabilities that we were really looking for. On the other hand Greenpois0n is a powerful tool which when injected into the iBoot, adds many powerful commands which allow you to do everything from accessing the AES engine to decrypt firmware keys, hook and call into existing iBoot functions, read and write to blockdevices, including the filesystem, and even set breakpoints within iBoot to dump registers and stack information during runtime.
He said that exploit he found couple of days was found and demonstrated by GeoHot in his iPod Touch 3G video couple of weeks ago. As far as Spirit Jailbreak of iPad is concerned, its far from being impressive pieces of work as such Jailbreak can be easily patched by Apple in its next firmware update. As the exploit resides in userland, you have no access to low level hardware features. On the other hand iBoot exploits allows you to have full access to system files.
He said the his team won't release the iBoot and Spirit exploit until the next hardware version of iPhone arrives but he guaranteed the exploit by the end of this month through which you will be able to Jailbreak iPhone OS 3.1.3 / 3.2 (All Devices - All Models). He advised all of the iPhone users to backup their SHSH before they may try the Jailbreak he will be releasing by the end of this month. If you don't know how to backup your SHSH then follow the guide here, iPad users should follow this guide to backup their SSHHs.
