We have seen quite a few announcements and demos from the iPhone hacking community about jailbreaking iPhone 3.1.3. But they still haven’t released tools to enable users to jailbreak their iPhones.
Joshua Hill, also known as p0sixninja from the Chronic-Dev Team has published a post, which explains the current situation and the reasons for the delay in releasing the jailbreaking tools.
p0sixninja starts off by providing information about their tool – greenpois0n:
Put simply, greenpois0n is a toolkit designed to help discover and exploit new vulnerabilities. Let me repeat that, greenpois0n itself is NOT an exploit. Most exploits typically have much more boring and technical names, such as “iBoot Environment Variable Overflow” or “usb_control_msg(0x21, 2)”.
And gives the reason for developing greenpoison:
Tools, on the other hand, are typically given more creative names, like redsn0w, blackra1n, or greenpois0n. Even though most of these tools use the same exploits, each one has its own unique strengths and weaknesses. Redsn0w was designed to be robust and low maintenance by using Apple’s own NOR flashing routines, whereas blackra1n was designed to be small, fast, and have a low memory footprint. While both these tools are excellent pieces of software, neither had the flexibility nor advanced capabilities that we were really looking for. Thus greenpois0n was born.
