Help the iOS 5.1 Jailbreak Community With Tips from Pod2g

Pod2g, the popular iOS hacker, just posted on his blog informing us all on how we can do our part  to help push along a Jailbreak for iOS 5.1. He explains what it takes to achieve a Jailbreak, and what everyone in the Jailbreak community can do to pitch in.  Be sure to follow @pod2g on Twitter and show your support!

Below is the blog posting via Pod2g’s iOS blog.

To jailbreak a device, hackers need a set of exploitable vulnerabilities :

• a code injection vector : a vulnerability in the core components of iOS that leads to custom, unsigned code execution.
• a privilege escalation vulnerability : it’s usualy not enough to have unsigned code execution. Nearly all iOS applications and services are sandboxed, so one often need to escape from the jail to trigger the kernel exploit.
• a kernel vulnerability : the kernel is the real target of the jailbreak payload. The jailbreak has to patch it to remove the signed code enforcement. Only the kernel can patch the kernel, that’s why a code execution vulnerability in the context of the kernel is needed.
• an untethering vulnerability : when the device boots, it is unpatched, thus cannot run unsigned code. Thus, to start the jailbreak payload at boot time, a code execution vector either in the services bootstrap or in the loading of binaries is mandatory.
